Navigraph FMS Data Manager does not open

First of all I am new here, so sorry for my first mistakes.
Secondly I live in Austria and my English could be better, but I’ll try my best…
Yesterday I downloaded Navigraph and I wanted to try out everything. One desktop- icon (Navigraph FMS Data Manager) refuses to open.
So I read several instructions from this sites. Nothing helped. Is there anything else I can do? As a newcomer I may have overlooked something on this website. It seems to be huge :-)!
Thank’s for helping me

Hi Ulrich,

Try restarting computer.

If still an issue,

I suggest a fresh start using exact procedure below :

Please disable any Antivirus and firewall. Uninstall AV if needed.

Use Windows to uninstall FMS Data Manager. Specifically:

  1. Press Start and open Apps & Features.
  2. On the right hand side, open Programs and Features.
  3. Find Navigraph FMS Data Manager in the list, select it, and press the Uninstall button above.

If they exist, delete folders:
c:\ProgramData\Navigraph and c:\Program Files (x86)\Navigraph.

Download and install latest FMS Data Manager .

Please let us know how you get on.


Hi Ian,

thank’s a lot for helping me. Of course it worked… Unfortunately I don’t know, which part of the forum’s description I left out.
Once again: Thank you very much.
