Little Navmap for Windows is a 32-bit application and was tested with Windows 7, Windows 8, Windows 10 (32-bit and 64-bit).
The macOS and Linux versions are both 64-bit and were tested with macOS Sierra and Ubuntu Linux.
Delete all installed files of a previous Little Navmap version before installing a new version. All files from the previous ZIP archive can be deleted since settings are stored in separate directories (except custom map themes). In any case do not merge the installation directories.
There is no need to delete the old settings directory. The program is written in a way that it can always work with old setting files.
The installation of Little Navmap does not change any registry entries (in Windows) and involves a simple copy of files therefore an installer or setup program is not required.
Do not extract the archive into the folder
c:\Program Files\ or
c:\Program Files (x86)\ since this requires administrative privileges. Windows keeps control of these folders, therefore other problems might occur like replaced or deleted files.
Extract the Zip archive into a folder like
c:\Users\YOURNAME\Programs\Little Navmap or
c:\Little Navmap. Then start the program by double-clicking
See First Start for more information on the first start after installation.
In some cases you have to install the Visual C++ Redistributable Packages for Visual Studio 2013.
Install the Visual C++ Redistributable Package if you get a warning about the SSL subsystem not being initialized. The program will not be able to use encrypted network connections (i.e. HTTPS) that are needed to check for updates or to load online maps.
Install both 32 bit (
vcredist_x86.exe) and 64 bit (
Usually this is already installed since many other programs require it.
You also have to install the redistributable if you get an error like
Error while checking for updates ... Error creating SSL context.
Little Navmap is a 32-bit application and was tested with Windows 7, Windows 8 and Windows 10 (32-bit and 64-bit). Windows XP is not supported.
You can find redistributable packages for all versions here: The latest supported Visual C++ downloads.
Other Simulators than FSX SP2
This program was compiled using plain FSX SP2 (no Acceleration) SimConnect version 10.0.61259.0.
You might have to install an older version of SimConnect if you use Prepar3D or FSX Steam Edition. If not sure about this simply try Little Navmap out. If it fails with an error message follow the instructions below:
Prepar3D: In the same directory as
Prepar3D.exe is a
redist\Interface directory (normally
C:\Program Files (x86)\Lockheed Martin\Prepar3D v4\redist\Interface). There are multiple legacy versions of SimConnect available. You have to install
FSX-SP2-XPACK.msi for Little Navmap.
FSX Steam Edition: The installation adds the folder
C:\Program Files (x86)\Steam\SteamApps\common\FSX\SDK\Core Utilities Kit\SimConnect SDK\LegacyInterfaces where you can find the legacy SimConnect interfaces.
Improve Start-up Time
Anti-virus program can significantly slow down the startup and execution of the program in Windows.
Therefore, it is recommended to exclude the following directories from scanning:
- Disk cache for map tiles:
- Scenery library and userdata databases
These directories to not contain executable files and are accessed frequently by Little Navmap.
Extract the ZIP file and copy the
Little Navmap application to the folder
Applications or any other folder.
Note on first start on macOS: When starting the application you will get a message
Little Navmap is from an unidentified developer. Are you sure you want to open it? or similar.
To bypass this right click or
Ctrl+Click on the application and select open. You probably have to enter an administrator name and password once. The program can be started normally after this procedure.
Extract the tar archive to any place and run the executable
littlenavmap to start the program from a terminal:
Most file managers will start the program if double-clicked.
Little Navmap can only connect to X-Plane using the Little Xpconnect X-Plane plugin which has to be installed as well.
The Little Xpconnect plugin is included in the Little Navmap archive but can also be downloaded separately. See the included
README.txt in the
Little Xpconnect directory for installation instructions.
The plugin 64-bit only and is available for Windows, macOS and Linux.
The downloaded Little Navmap archive contains two additional directories (or applications for macOS):
Little Navconnect: A complete copy of the program allowing remote flight simulator connections for FSX, P3D and X-Plane.
Little Xpconnect: This is the 64-bit plugin that is needed for Little Navmap or Little Navconnect to connect to X-Plane.
