The current version of Citadel Remonstered with GOG file version 1.0.7_(90511) does not run on Windows 7 x64, not weven with an Windows 7 API Extender like VxKex-NEXT..

Error
Unable to start program "citadel.exe". "citadel.exe" is not a valid Win32 application.

Is there a way to get a Windows 7 compatible executable or another way to run it on Windows 7?

There is no easy way because some of the component dependencies in the game require Win10+ due to security considerations over Win7 being unsupported. It would require a re-build of the game with some older components which could be considered insecure and also impact some of the game functionality.

Thanks for the answer, I already guessed so.
