After I did a clean reinstallation of Prepar3D v3 it seems that I can't install GSX anymore.
Everytime I run the installer there is a error message during the intstallation process:
F:\Prepar3D v3\fsdreamteam\couatl\gsx\sounds\ ...
An error occurred while trying to read the source file:
The source file is corrupted
[...]
It seems every sound file is currupted. What can I do now?
