Updated FMS Data Manager not launching


I turned on my PC this morning and got a notification that a new FMS Data Manager was available, and to click to install. I followed the instruction and an installer ran, and then requested a restart of my PC, which I did.
However, now when I try to launch the FMS Data Manager Windows first asks if I want the app to make changes to this PC, but when I click Yes, nothing actually happens, except it appears to create a NGFMSManager_[date&time].dmp file in its folder. Task manager seems to confirm nothing actually running.
Version is
I’m running Windows 10 Pro 64-bit.

Thanks in advance for your help

Hi Kevin,


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.


Thanks Ian,

I’ll give that a shot later today and report back.



Hi Ian,

Unfortunately that didn’t fix the problem. I completely removed the previous FMS Data Manager as you described and then re-installed it. However I’m now getting the exact same symptoms as previously. When I attempt to launch it (even as Administrator) the blue spinner appears for about half a second and then nothing else happens.

I grabbed the following Error from the Event Viewer Application log:

2 posts were split to a new topic: FMS Data Manager Problem

you wrote in your first post, that “the app wants to change anything on your PC”. Please can you make a screenshot of this message … is it the UAC message or any other one?

Further, do you use a local account or a Microsoft account?

And last, can you give us your exact OS version please, patch level, …

Thank you

Sorry for the late reply. Haven’t been able to get on the home PC for a couple of days.
The message in question is just the standard one Windows 10 gives for some apps. I wasn’t able to screenshot it for some reason as that doesn’t seem to work when it’s on the screen, so I took a photo instead.IMG_1329
I’m logged in with a Microsoft account.
Windows 10 Pro
Version 2004
OS Build 19041.867
Hopefully that’s all you need?

You have a PM Kevin :wink:

Thank you very much,

Dear all,
I encounter on a similar problem of the topic. After have downloaded the latest version, I’m not able to run it. Or, it seems that the app is on but I cannot see the interface. I’ve disabled the antivirus and firewell.
Any idea?
Many thanks!!

Hi Fede
can you try following:
Close the application (possible look in the taskmanager or reboot your system)

Goto %ProgramData%\Navigraph\FMSClient and rename the setting.config file to any other filename. After that restart the Application and login again.
