. up


Installing the software with the Dongle and CD.

Be sure to install the dongle drivers. These are on the CD that came with the dongle. 
A small (sometimes weak) light at the end of the dongle testifies to the proper installation of the dongle.

From ScanNav DVD version 14.0 or higher: (works on all versions of Windows)
-Click on the "install dongle" button of the window that opens by inserting the cd. A window opens and closes quickly. Then only after, plug the dongle. The Windows detection procedure then begins. Click Next at each step (needless to ask him to search the internet) 
It is also possible to fetch the drivers manually in the \ Installer \ DriversDongle directory of the CD-Rom. Choose the subdirectory 32 or 64, depending on the version of your Windows (32 or 64 bits) 

Older DVDs (or CDs): (some problems encountered on Windows 8)
-On the standard 32-bit versions of Windows, click on the "install dongle" button of the window that opens by inserting the CD. Then plug in the dongle, which will trigger the procedure for detecting new Windows device. Click Next at each step (needless to ask him to search the internet) 
-On 64-bit versions of Windows Vista and 7, it will be necessary to indicate to it the location of the drivers if it does not find them automatically: these are in the directory "Installer \ DriversVista64bits" of the CD-rom. 

Download: (works on all versions of Windows) 
If you have lost your DVD, or if it is too old to contain 64-bit drivers or Windows 8, you can download the latest version of the drivers on the following link: 
Once the archive has been downloaded and uncompressed, go to the "driversdongle" directory and double-click on the "install.exe" file. It is also possible to search the drivers manually in the 32 or 64 directories, depending on the version of your Windows (32 or 64 bits). 
As for installation from the DVD, you should only connect the dongle after installing the drivers. 

What to do if the dongle is installed incorrectly: 
In case you have not installed the dongle the first time, Windows may assign a bad driver, it will uninstall. To do this, go to the device manager (the dongle is connected), and locate a yellow icon that will be indicated "unknown device" or "Spark dongle", right-click on it then: 
  • if you are on a 32-bit version of Windows: choose "uninstall", then unplug the dongle, reconnect it, and follow the Windows new device detection procedure (you must first have done the procedure described above "install the dongle ")
  • if you are on a 64bits version of Vista or Windows7 / 8: choose "update the driver", then "search for the driver on my computer", then click on "browse" and go to the directory "Installer \ DriversVista64bits" CD-ROM, and continue clicking on "next". 

Then you must register the license on the Internet to activate it . The dongle must be connected. The PC used for recording can then be used with this license without requiring the dongle, and the same license can be used on any PC with the dongle connected. 
-click on "Get the license" 
-or in ScanNav go to the menu "?" => "Registration / License Application"

Then simply follow the instructions on the screen. The easiest way is to use the "automatic recording" mode if the pc is connected to the Internet. Otherwise, follow these 3 steps: 
1) on the PC intended for use: click on the -1- button and save the resulting file 
2) on a connected PC (you have to install the demo version of scannav), click on the button -2- and go for the file from the first step. Then save the resulting file. 
3) on the pc intended for use: click on the -3- button and go to the file resulting from step 2. 

On the following screens, fill in the last name / first name and email, as well as the product code on the label inside the dvd box (or the one that was sent to you by email) to validate the license. 



Dongle installation without CD player.

Just copy the contents of the CD-ROM with a USB stick or other. The directory Installer is enough. 
Then run the CDInst.exe executable in the Installer directory, then click on "install dongle" BEFORE plugging in the dongle.

In case of recognition problems please refer to the previous chapter



Installing old (*) licenses on a 64-bit version of Windows:

Licenses for older versions of ScanNav were distributed via a registry file. Almost all versions of Windows were then 32bits, a simple double click on the file was enough to activate the license. 
Windows 64bits versions have appeared since, and the management of the register being slightly different, it requires a slightly more complex manipulation to introduce the old (*) licenses: 
  1. Click Start , and then click Run on the Windows menu 
  2. In the Open box , type % systemroot% \ syswow64 \ regedit , and then click OK .
  3. In the window that opens, click on the " File " menu and then " Import "
  4. Browse the file system to fetch your license file (.reg extension), then click Open . 
(*) This problem does not exist on the updated versions of ScanNav licenses, the recording mode has been adapted.



Installing Primar ENC Charts

NEW : from version 11.5, see the new procedure here: DocInstallENC.pdf

The following is still valid for older versions:

Simplified procedure: 
A zip archive is provided for download when you order. Just unzip that archive to your hard drive, then insert the enc.pmt file from the ENC_ROOT directory into your map library. For updates, refer to the standard procedure with the S63Install tool.

Standard procedure: 
The 2 permit.txt and enc.pmt files delivered must be copied to the ENC_ROOT directory or the ENCs will be installed (see S63Install documentation). Copy them in place of the existing files.

The tool for downloading ENCs with its documentation is integrated into the ScanNav installer. They are accessible via the windows start menu in the ScanNav directory: 
- S63Install documentation: documentation 
- S63Install: download / update tool

The tool still has some minor flaws of youth, and you have to follow the instructions scrupulously. 

Alternatively , you can also use the Primar Online service which involves copying the directory and files to the right place. You can access it via the primar catalog by clicking on the button with a small globe, and by filling in your User-permit

CAUTION : When ordering new orders, new licenses do not include old stale cells. In order to continue using these cis-cis, the easiest way is to use a different ENC_ROOT directory for the new cells, you can treat them independently by including the 2 in the scannav library. 
For example, if your file for old ENC is "C: \ Maps \ ENC_ROOT", you can use "C: \ Maps2 \ ENC_ROOT"

Then in ScanNav, insert the cells into the ScanNav charts library by looking for the file enc.pmt in the directory ENC_ROOT, where you copied it, which will insert all the cells in one operation:

  • Open the map library window: use the first button on the toolbar  , or the "File" menu -> "Card Library"
  • In this new window, use the menu "File" -> "Insert charts or libraries"
  • In the file chooser that opens, move to the ENC_ROOT directory,
  • Select the file enc.pmt and click on the button "Open"



Installing Navionics Charts

NEW : from version 11.5, see the new procedure here: DocInstallNavionics.pdf

The following is still valid for older versions:

Navionics charts are distributed on SD-card or CF-card, and require the specific Navionics reader to be able to decode them (A standard reader is not enough).

  • Insert the SD or CF into the drive and plug it into a free USB port
  • Windows will detect 3 new readers. (eg E: F: and G :, variable depending on the disks or other devices already present)
  • Normally, the first letter corresponds to the CF-card and the 2nd letter to the SD-card but it can change.
  • The charts are in the [X] subdirectory: \ Navionic \ Charts (replace [X] with the player).

How to release a USB port: 
You can read the charts directly from the media, or copy the full contents of the media to your hard drive (be careful not to remove them from the drive) , and tell ScanNav to search for them on the hard drive rather than the media. USB. This will release a USB port in use, and will accelerate a little access. However, the drive with the original physical media inserted must be plugged in at startup to initialize the decryption of the charts.

To insert the charts into the library: 
  • Open the map library window: use the first button on the toolbar Library , or the "File" menu -> "Card Library"
  • In this new window, use the menu "File" -> "Insert charts or libraries"
  • In the file picker that opens, go for the charts (.nv2 extension files) where you copied them or on the original drive.



Installing Maptech charts

Maptech charts are distributed on CD-ROM and must be registered for use. The system is completely independent of the license ScanNav, Maptech authorizes the unlocking on 2 pcs.

See the complete procedure here: Inst-Maptech-DVD.pdf 

Problems installing Maptech charts on Windows 7 and above

If you can no longer open your Maptech charts, first check the following:

  • Check that you have activated the Maptech license as described in the document Inst-Maptech-DVD.pdf
  • If you have deleted or moved your charts in the Windows file structure, ScanNav will not find them anymore (this is valid regardless of the type of charts): search the files on the disk, and restore them to their location. origin, or rebuild your library by inserting the charts from their new location, or redo the installation of the charts.
If the problem persists after these checks, and you are running Windows 7 or later, the problem is probably a Maptech licensing problem that is not compatible with the latest versions of Windows for recent applications. This problem has been reported to Maptech, but they refuse to treat it, under the pretext that they no longer support their products outside the US zone. 

The cause of the malfunction has been identified, however, and is related to the administrative rights of Windows. 
Since the problem is of Maptech origin, and having no control over it, we can only propose workarounds, with the following possibilities: 

A) Handling the installation of Maptech charts: 
This procedure consists of modifying the access rights of certain keys of the Windows registry and requires a little technicality. 
Be careful , before you start in this step, check the points mentioned above, otherwise the manipulations will be useless. If you do not feel comfortable with the regedit tool, we strongly advise you to be assisted. ScanNav disclaims all liability for mishandling that may be fatal. 
The procedure is deliberately described briefly in order to reserve it to connoisseurs: 
  1. Activate the Maptech DVD in administrator mode: right-click on the "Register.exe" executable of the dvd, and choose "Run as administrator"
  2. Then use regedit and change the access rights to "Total Control" for users to the following registry key (and its subkeys): "HKEY_LOCAL_MACHINE \ SOFTWARE \ Wow6432Node \ Maptech \ ChartKit"
B) or Disable the UAC in Window 
This manipulation consists of going into the Windows settings and turning off the UAC. Also requires a bit of technicality, and has strong counterparts at the security level. Although it helps to unblock the situation, we do not recommend it. Refer to the Windows documentation. 

C) or Run ScanNav in administrator mode 
An alternative solution is to run ScanNav in administrator mode. It is not recommended either, because can have unmaintained impacts by switching from administrator mode to standard mode, including settings, licenses, and file access rights. 

D) or Downgrade the system to Windows XP, or use an earlier version of ScanNav 
These solutions are of course not recommended , and for good reason: 
  • The latest version of ScanNav that can use Maptech charts without special handling is the 14.1SP2 version which was generated with the same old Microsoft tools as those used by Maptech. However, this version is no longer supported and will not evolve, the ScanNav compilation tools have been updated to take advantage of the evolutions of Windows.
  • Windows XP is no longer supported by Microsoft (but still works with the latest versions of ScanNav)
Maptech no longer provides support, and their latest updates for the Europe area are excessively old, the recommended solution is to change the map offering , to use SnMap charts, Navionics charts , or official ENCs



Demonstration charts

The installation of ScanNav only comes with a small scale base map. To test with detailed maps, you can use the royalty free maps of the US and Brazil, downloadable on their respective sites: 

1) Noaa US ENCs : http://www.charts.noaa.gov/ENCs/ENCs.shtml 
Read the disclaimer and go down the page to click on the "Proceed to Download" button 
On the new page, click on the ENC link: " Click Here to Download NOAA Electronic Navigational Charts .Then follow the instructions. You then have the choice of different areas to download. Either download the whole, by clicking on " All ", or a complete state by clicking on the corresponding state, or cell by cell. 
The result of your selection will be downloaded as a zip file to unzip into a blank directory on your computer. 
Then in ScanNav: 
  • Open the map library window: use the first button on the toolbar Library , or the "File" menu -> "Card Library"
  • In this new window, use the menu "File" -> "Insert charts or libraries"
  • In the file chooser that opens, move to the ENC_ROOT directory,
  • Select the CATALOG.031 file and click on the "Open" button, which will insert all the charts in the library.
2) US Noaa Raster Charts: http://www.charts.noaa.gov/RNCs/RNCs.shtml 
Choose on the site the charts to download, which will bring you a zip file to decompress on your computer (download procedure similar to that of the ENCs described above). 
Then in ScanNav: 
  • Open the map library window: use the first button on the toolbar Library , or the "File" menu -> "Card Library"
  • In this new window, use the menu "File" -> "Insert charts or libraries"
  • In the file picker that opens, move to the unzipped directory
  • Select all the extension files ".KAP" then click on the "Open" button (use the classic Windows multi-selection with the <Ctrl> key on the keyboard then click on each element, or "<Ctrl> A" for all to select.
3) Brazil Raster Charts: 
The maps are downloadable individually. Go down the page to view the list, and click on the links of the maps you want to download, which will bring you as many individual zip files (one for each map). You can unzip them all in the same directory for easy insertion into ScanNav. Then in ScanNav, use the same procedure as the Noaa Raster charts described above. 

4) Maps of Marine Protected Areas: 
SHOM broadcasts maps of Marine Protected Areas of the French coast free of rights. His charts have been converted to SnMap format and can be used as demo charts. Do not use for navigation. You can download them at the following links: 
- Install for Windows version: http://www.scannav.com/PacksRaster/download/PackAiresMarines.exe Double click on the downloaded file, then follow the instructions on the screen. 
- Zip format for ScanNav Companion: http://www.scannav.com/PacksRaster/download/PackAiresMarines.zip Follow the instructions in the Companion documentation 

5) New Zealand Raster Charts:

Crazy mouse

The "crazy mouse" syndrome is a recurring problem of Windows, recognized by Microsoft.

In some cases, the connection of a GPS receiver antenna or other instrument is seen as a mouse and therefore creates a conflict with the real mouse, moving the cursor in all directions.

Solution for Windows XP / NT / 2000/98

One solution is to set Windows startup to tell it to ignore the serial mouse by adding one of the following options to the boot parameters: 

/ fastdetect 
/ NoSerialMouse 
/ NoSerialMice 

A priori, for Windows XP it is / fastdetect . But unfortunately, the docs are not clear, so if it does not work with / fastdetect , use one of the / NoSerialMouse or / NoSerialMice options . For an explanation of the startup parameters, see the article http://support.microsoft.com/kb/833721/en

Here's how to proceed:

You have to modify the file "Boot.ini" which is at the root of the boot disk (C: normally) 
First of all, Warning: modifying the Boot.ini file is an operation that can be dangerous in case of mishandling. Be careful not to change anything other than what is described below.

This file is a hidden file. You can access it in several ways:

1) First method: 
- use the windows menu "start" -> "Run" 
- type "C: \ Boot.ini" in the window ==> the file must open the file with Notepad

2) Second method: 
- Click with the right mouse button on the workstation, then on "Properties", 
- Select the "Advanced" tab 
- Click on "Settings" under "Start and recovery" => open a new window 
- Click "Edit" under "System Startup" ==> This opens the "Boot.ini" file in Notepad

3) Third method (not recommended for expert nons): in the display settings: uncheck "hide protected files of the system", then open the file C: \ Boot.ini with notepad

Once this file is open with one of the methods above, you will have content that will look like this:

[boot loader] 
timeout = 30 
default = multi (0) disk (0) rdisk (0) partition (2) \ WINDOWS 
[operating systems] multi (0) disk (0) rdisk (0) partition (2) \ WINDOWS = "Microsoft Windows XP Home Edition" / noexecute = optin

==> Add the option "/ fastdetect" at the end of the line starting with "multi", you will have the following content

[boot loader] 
timeout = 30 
default = multi (0) disk (0) rdisk (0) partition (2) \ WINDOWS 
[operating systems] multi (0) disk (0) rdisk (0) partition (2) \ WINDOWS = "Microsoft Windows XP Home Edition" / noexecute = optin / fastdetect

-Save the file 

If the problem persists, try replacing / fastdetect with / NoSerialMouse or / NoSerialMice 
And if in spite of all this continues, there is also another solution a little more complex by modifying the registry, described here: 

Solution for Windows 7 / Vista

Although a priori less common than on XP, the problem can also occur on Windows 7 and Vista. As the startup procedure of Win7 and Vista is different, what is stated above for XP does not work.

Before going any further, first check the version of your GPS driver or USB / Serial adapter. If the driver is not provided, you must be able to download it from the manufacturer's website. Most USB GPS and / or Serial / USB adapter using the Prolific chip, you can also download it from the Prolific website

If the problem persists, you can try the procedure explained on the microsoft forum: click here 
This procedure involves modifying the Windows registry, so be careful and follow the instructions carefully.Alternatively, you can use the downloadable registry file here

  • download the file disablesermouse.zip
  • Unzip the downloaded zip
  • double-click on the file "disablesermouse.reg" extract, and accept the security warnings
  • Restart Windows
  • According to the comments of the Microsoft forum, it is possible that the problem reappraises later, in this case repeat the procedure.



"Invalid descriptor" error when loading maps

If you have this error message, you have not followed the procedure ;-) 
To insert charts in the ScanNav charts library, use the file menu of the " charts library " => " insert charts or libraries ", not "open library" which is made to open charts libraries scannav already constituted.

To open the Charts Library window, use the first toolbar button  , or the "File" menu -> "Charts Library".



License Activation Issues

Windows Firewall Issues

If an error message appears during activation, your firewall may be blocking access to the Internet for ScanNav.Try to temporarily disable your firewall, and try again. Do not forget to reactivate it once the license is activated.

If this solves the problem, we advise you to set your firewall to let ScanNav pass. The affected program is ScanNavFR.exe in the ScanNav installation directory. (refer to the documentation of your firewall / Antivirus)

Note : The firewall issue can also impact the GRIB file download. In this case, the program to pass is GribRequestor.exe , also in the installation directory of ScanNav.

Problems with accents (fixed in version 17.1)

A problem appeared on the use of accents in the first and last names given in the activation form. It is characterized by an error message during activation, with the code "http / 1.0 400 Bad request". This problem has been fixed in version 17.1 of ScanNav.

For older versions, avoid using accents in the form. For example, use "Francois" instead of "François", "Celine" instead of "Céline", etc.

Old License Loss Issue (fixed in version 13.2)

This issue has been escalated due to the latest Windows updates.

Description: You activate your product code online, the system tells you that the license has been activated , but when you leave, you are still in demo version.

Recommended solution: update ScanNav and redo online registration (if your license is too old, you must subscribe to the 25 € update, see http://www.scannav.com/GB/order2.php )

Or, if you want to keep your old version prior to version 13.2 ( do not apply this method for updated ScanNav versions )

Activate the license in administrator mode:

  • Start ScanNav in administrator mode: right-click on the ScanNav icon on the desktop, and choose " Run as administrator "
  • Do the registration procedure
  • Quit ScanNav
  • Restart ScanNav in normal mode, and check if it is ok.
This problem should no longer occur from version 13.2



GPS recognition issues and other Instruments

The most frequently encountered problems are the setting of GPS and other instruments, which must be taken care of in the preferences of ScanNav. Here is a small checklist of things to check before reporting a problem.Refer to the documentation for more details on the parameters. 

Typical Question : I can not get my GPS to work. 
Typical Answer : I need more information to help you out. First check the following points: 

  • Did you perform instrument setup in the ScanNav preferences?
  • Make sure you listen gps via the button GPS ?
  • If there is an error message what is its exact content?
Once these questions are answered, most issues are resolved. If there is no error message, it is usually a problem of understanding and not activating the GPS. In other cases, there is always an error or warning message. 

Communication problems with GPS 

The error messages can be among the following: 
  • Error upon opening: "port com (or file) does not exist" => no existing driver for this port number. Change COM port in preferences (See "No communication with the port")
  • Error opening: "The process can not access the device", or "create file (\\. \ COMx) Access denied" => Occurs if another program accesses the same com port at the same time (eg tool gps test). Stop the other program and that should fix the problem (only one software can access a COM port at any given time) 
  • "No communication with the port" => There is an existing driver in Windows, but it receives nothing at all.Possible causes are:
    • the COM port set in the preferences is not the correct one. Try changing the setting of the COM port number in the preferences. The list of existing COM ports should appear in the Windows Device Manager, under the heading "Ports (COM and LPT)", with a textual description that should help determine the correct port (it should be "USB adapter", or something like that). Tip : When connecting / unplugging the GPS or USB adapter, you must see the corresponding COM port entry appear / disappear in the device manager.
    • either there is a problem of connection on the cable (cable sectioned or badly connected, etc ...)
    • the gps does not transmit any information (unmeasured nmea output on it, etc ...)
    • Also check that the USB adapter has been installed in Windows.
    • Your GPS may not be set to NMEA 183, but to another protocol. For example some Garmin GPS that use the Garmin protocol, or a NMEA 2000 connection. In this case, choose the appropriate model in the preferences. 
  • "No receipt valid position" => There is something that sends information to the other end, so there is a good chance that it is the GPS if no other instrument is connected. However ScanNav detects nothing in what it receives that can be interpreted as valid position information. This can be due to different causes:
    • GPS coverage problem: this is the most common case, for example if you are testing inside a building, or the GPS does not pick up satellites. 
    • Parameterization problem in the preferences: check the speed settings, etc ... and the checksum parameter (some gps do not send valid checksum)
    • Problem of setting of the GPS: to check that it is well in NMEA 183 with the good speed etc ... 
    • Faulty wiring problem: false contact, etc ...
    • Or if it's just not a gps that is connected ...
  • If the boat is correctly positioned, but the messages "No communication with the port" and / or "No valid position reception" appear only momentarily from time to time (they are displayed, then disappear by themselves) , this means that the connection parameters are good, but that the GPS sends its information at a lower than normal rate. In this case, increase the "Maximum Time" delay in the preferences.

Communication problems with other instruments

The symptoms are the same as for GPS, with a few particularities, in particular as regards the AIS: 

  • The AIS sends its information in NMEA 183 "Hight Speed" and must be parameterized with a speed 38400bds. The other parameters being identical to the other instruments. There may be variants depending on your connections, check that the parameters of your control panel or AIS box are configured with the same parameters.
  • Some AIS send no other information when there is no target in sight. In this case, it is necessary to increase the maximum times without communication and without valid reception to avoid having false alarms. If you are sailing offshore, do not hesitate to enter huge values ​​(eg 86400 for 24h).

If despite these checks the fault persists, do not hesitate to contact us with suggestions maximum details on the problem, if possible with a log of the information received (In the preferences, set "Save NMEA sentences Log in the directory" ) 



Bug on Old GPS devices from April 6, 2019

A bug appeared on some old GPS starting April 6, 2019, and resulting in an incorrect date. For more details, type "GPS Bug April 6th 2019" on your favorite search engine.

The best way to correct the problem is to update the firmware of your GPS, if the manufacturer offers the possibility. However, this is unfortunately not always the case..

ScanNav therefore provides, from version 20.0, a solution to this problem with specific settings. As it consists in advanced settings which can result in malfunctions if it is used improperly, please contact us for more information if you are affected by this problem.
