3. Installation

Little Navmap for Windows is a 32-bit application and was tested with Windows 7, Windows 8, Windows 10 (32-bit and 64-bit).

Windows XP and Windows Vista are not supported.

The macOS and Linux versions are both 64-bit and were tested with macOS Sierra and Ubuntu Linux.

3.1. Updating

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 Creating 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 work with old setting files.

3.2. Windows

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 directory c:\Program Files\ or c:\Program Files (x86)\ since this requires administrative privileges. Windows keeps control of these directories, therefore other problems might occur like replaced or deleted files.

Extract the Zip archive into a directory like c:\Users\YOURNAME\Documents\Little Navmap or c:\Users\YOURNAME\Programs\Little Navmap. Then start the program by double-clicking littlenavmap.exe. The extension .exe might be hidden in Windows Explorer depending on settings. In that case look for a file littlenavmap having a light blue globe icon.

See Introduction for more information on the first start after installation.

I recommend to install the Visual C++ Runtime Installer (All-In-One) v56 package from MajorGeeks.Com but only if you get errors when starting Little Navmap.

3.2.1. 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 directory C:\Program Files (x86)\Steam\SteamApps\common\FSX\SDK\Core Utilities Kit\SimConnect SDK\LegacyInterfaces where you can find the legacy SimConnect interfaces.

The needed SimConnect package is also available at Little Navmap Downloads - SimConnect FSX SP2.

3.2.2. 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: C:\Users\YOURUSERNAME\AppData\Local\.marble\data
  • Scenery library and userdata databasesC:\Users\YOURUSERNAME\AppData\Roaming\ABarthel\little_navmap_db

These directories do not contain executable files and are accessed frequently by Little Navmap.

3.3. macOS

Extract the ZIP file and copy the Little Navmap application to the directory Applications or any other directory.


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?

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.

3.4. Linux

Extract the tar archive to any place and run the executable littlenavmap file to start the program from a terminal:


Most file managers will start the program if double-clicked.

3.5. X-Plane

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 is 64-bit only and is available for Windows, macOS and Linux.

3.6. Additional Programs

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.
