The game cannot be started, the following error message appears:

The Windows Registry entries for this program are corrupted. Please Re-install Fallen Haven.

Unfortunately, running as an administrator doesn't do anything!

Does somebody has any idea? Thanks in advance

installing in the directory

C:\I-Magic\Fallen Haven

AND

C:\Windows\I-magic\Fallen Haven

does not work

I just had the same problem. I installed it to C:\I-Magic\Fallen Haven through Galaxy and it didn't work. Then I installed it there with the offline installer and ran the .exe directly and then it did work. Did you use the offline installer and open the .exe?
