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 .

Please let us know how you get on.

Hi Ian,

First of all thanks for your help.

I have the same problem than Paul5287, and I did step by step all the procedure that you said. But unfortunately it did not work for me. Any recomendation? It’s really frustrating this situation.

Thanks in advanced.

Thanks Jero …

So, do following please:
Look into your task-manager, that the FMS Data Manager is not running, than please delete the “settings.conf” file from here %ProgramData%\Navigraph\FMSClient.

After you have done it, restart the FMS Data Manager and send me the latest log file again please.
Do you have a multi-monitor equipment?

Thank you very much

Hi Richard,

No, I do not have multi-monitor.

I did delete the file settings.conf. and here you have the latest log file:

20210415-190911.log (408 Bytes)


Now is working!!!

thank you so much Richard!

I owe you a beer!!


Please check again, if all instances/processes of the FMS Data Manager are really down … you see in the log-file, that the FMS Data Manager can´t be started due multiple instances

So, please make 100% sure, that all processes in the task manager are really killed:

After that, try the same again … delete the settings.conf file and start the FMS Data Manager again. Then the log file please.

Thank you,

Hi Richard,

So sorry, but one more time i am having problems. Initially i worked but after sign in into my acount of Navigraph the problem appear again.

Hi Jero,
the problem is the window, which you don´t see I guess. The application starts somewhere in the background and therefore you see no result.

Please send me your settings.conf file per private message, not here via the public form please :wink:
Thank you,

HI, I did it. And here you have the latest log.

Yessssssssssssssssss :slight_smile:

The good news for you … the FMS Data Manager works on your system. The log is complete and shows this, but something is strange with your screen-settings.

So, please send me your settings.conf file via a PM please (click simple on my picture and press the “Message”-button), that I can check this settings.

Thank you - we are near a solution - 100%

PS: I also guess, that the reset to “default position” in the application doesn´t work as expected in this situation … but thats my part

Hi Richard! Done. I sent you the file.

a short summary. I had a private mail session now with Jero (@jeromegallardo1978) and during this session, I have figured out, the issue why you don´t see the window. It´s a bug in the FMS Data Manager and I apologize me for this mistake.

I know now, where the issue is and I´m start to fix it but please give me a little bit of extra time. I will inform you here, when the working version is available for you!

Thanks again to @jeromegallardo1978 for their help in this case. Great stuff … Thanks Jero!

PS: this topic will be still opened, till the issue is fixed!
