Fms data manager

Have been using navigraph fms data manager. Today when I opened it I was prompted with an update. Ran the update and I am unable to open the interface. It appears in my system tray and when I click open interface nothing happens. I uninstalled and deleted the folder and ran a fresh install and still not having any luck.



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 .
