QT Plugin not found in Windows 10

After starting my Windows 10 computer a pop message recommended updating the FMS Manager which I did.

Now FMS Manager will not start. I get this error:

NGFMSAgent: This application failed to start because no QT platform plugin could be initialized. Reinstalling the application may fix this problem. Available platforms are: Windows.

I have reinstalled FMS manager 3 times, updated all Windows 10 updates, restarted multiple times. Nothing fixes it.



Hi Lee,


We have on occasions found some difficulties with the uninstall of FMS Data Manager.

I suggest a fresh start using exact procedure below :

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

If you have backups of previous AIRACs you wish to keep, backup c:\ProgramData\Navigraph\FMSClient\backup

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\FMSClient and c:\Program Files (x86)\Navigraph\FMS Data Manager.

Download and install latest FMS Data Manager .

Please let us know how you get on.
