I see you have been a customer for many years, thank you.

What has changed on your system since it was working , Windows Update, AV update . software update ?

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.


Hi Ian,

Thank you for getting back to me.
I have followed your steps and uninstalled FMS Data Manager.
Then I removed the folders you suggested and disabled Windows Build in FW and A/V.

I installed the latest and the issue seems to be resolved!

Don’t know what was the cause (either the FW/A/V or the removal of Program Files / Navigraph/ FMS Data Manager) either way the issue is resolved.

Hi Dekel,

You are welcome. Sometimes starting from scratch solves it, and gets us to the same starting point,

Happy flying.
