Hi everyone,

I am trying to install Allplan 2017 on a new Windows 11 PC (64-bit), but the setup aborts with an error message saying that the operating system is not supported.

I have already tried the following without success:
- Compatibility mode (Windows 10) on setup.exe
- Windows ADK Compatibility Administrator with WinVersionSpoof

I have seen in older threads that other users have managed to solve this problem. Unfortunately those threads are now closed.

Would anyone be able to point me in the right direction?

Thank you very much in advance!
