FMS Data Manager ERROR

Using Windows 10 64 bit latetest updates, using xplane 10 latetst update, using Navigraph software latest update

When opening the FMS Data Manager, I will get a message "Microsoft Visual C++ Runtime Library - Runtime Error
R6034 - An application has made an attempt to load the C runtime library incorrectly. Please contact the application’s support team for more information.

Anyone else that message ? And what is the solution?

It seems that FMS Data manger is updating my data anyway.

Thx for helpingError Message

there is no solution for that at the moment - here the a link to this “story”. It´s not really a FDM issue it´s more a config issue on your system, but I can´t verify it and I can´t reproduce it - I need help from someone who has this issue. I need a remote-session to look on a system - sorry.


Hi Richard, thank you for quick answering. I will look forward to a solution though.

have the same problem with the same error R6034 on my Win10 64bitlatest update! When updating or installing the latest version of the FMS Data Manager the Visual C++ redistributable 2015-2019 (x86) pack automaticly will be installed. Why??
No problems before the newest update.
Best regards

is it possible to look on your system via a remote-session? … The Redist 2015-19 is necessary for the QT update what we have made.

Hi ,
yes Redist 2015-2019 (x86 and (x64) is installed , see screenshot.

Regards pilotxpl737

is it possible to look together on your system via a remote session?


I have the same issue, and the only difference that I can see is:
MS C++ 2015-2019 Redist. (x64) 14.28.29334 (rather than 29919)
I’d be happy for you to remote into my sim.
Please let me now.
