What I forgot to mention in my previous post - I ran wine as root after upgrading (just in a terminal) and got the following output: Converted temp dir to new entry HKCU\Environment "TEMP" = L"e:\\" Converted path dir to new entry HKCU\Environment "PATH" = L"c:\\windows;c:\\windows\\system;e:\\;e:\\test;f:\\" Converted profile dir to new entry HKCU\Environment "USERPROFILE" = L"c:\\windows\\Profiles\\Administrator" Converted windows dir to new entry HKCU\Environment "windir" = L"c:\\windows" Converted system dir to new entry HKCU\Environment "winsysdir" = L"c:\\windows\\system" No idea if that's at all significant...
