I have been using GOflight's MCPPro on WIN 10 without any issues.  Recently, I've had to install a new motherboard, cpu, and WIN 11Pro.  To get the MCPPro to work on the MSFS defaults you have to install the GF setup which includes the drivers and the app GFDevFSX.  Everytime I try to open the GFDevFSX app I get the following error, 

"C:\Users\g113\OneDrive\Desktop\MSFS\GoFlight\GFDevFSX.exe

The application has failed to start because of it's side-by-side configuration is incorrect.  Please see the application event log or use the command-line sxstrace.exe tool for more detail"

I have tried all that with no help.  I've also tried uninstall/reinstall and it's always the same.  Any computer geeks know what this is all about?  I've mention this problem on many forums with no help.

Thanks in advance,

Gnacino
