Unable to update to cycle 2208 with FMS Data Manager

Update to cycle 2208 with FMS Data Manager stop working at “Preparing for installation… “

The problem persisted after a careful uninstall of FMS Data Manager (based on this forum recommendations) and new installation (with administrative privilege) with the last version of the software and my firewall and antivirus (Bitdefender) off.

Thank you for your advice

Hi Philippe,


I suggest a fresh start using exact procedure below :

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

In FMS Data Manager Settings Unregister Account:

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 to the default location.

Restart computer.

Please let us know how you get on.

Hi Ian,

And thank you for your answer.
I had already done the procedure you suggest.
However, I tried again this morning without success.
But I found the culprit.
As the process gets stuck at different stages, I suspected a problem with the network settings.
I uninstalled the latest update of iolo System Mechanic Pro and restored the default network settings.
This solved the problem.

Thanks again for your help and your fantastic products

Happy flying.
