--- Comment #13 from hennr hennr@hennr.name 2011-06-20 11:01:58 CDT --- I just wondered if I can reproduce the bug...
It seems that I have to rewrite the bug report.
I can (using wine 1.3.22) install and uninstall the game demo. But if I start the Installer again, the game gets detected as installed, which is wrong and the (un-)installer crashes as described in the bug report.
