Hello Umberto!
I'm done with my next test.
I have now deleted all my liveries and individually reinstalled and tried them out.
With every livery I have (except for the original FBW) you have the problem.
Cannot create a gsx.cfg when trying to create from these liveries.
It only works with the two originals from FBW.
All liveries are downloaded from "Flightsim.to".
I have several from Flightsim.to and all have the same result.
Further tests with the liveries.
1. I installed the liveries with the additional programs ModManFX64 and MSFS_AddonsLinker. No success.
2. Copies the liveries directly to the community directory. No success.
3. With a successful gsx.cfg from the original FBW liveries, I also tried the other liveries and hoped that it would work. But unfortunately it is not recognized and an unedited setting is displayed again.
Here is one of the liveries I used:

thanks benne
