--- Comment #5 from Anastasius Focht focht@gmx.net --- Hello folks,
--- quote --- I can say I just did a clean prefix, installed .NET 4, made sure Windows XP is the Windows version, and ROTT's launcher still crashes. Honestly, I've had this game work before but .NET applications seem to run or crash randomly in my experience. --- quote ---
Just re-downloaded and installed that 7 GB game from Steam in 32-bit WINEPREFIX ... works like a charm.
Either I have the "golden" Wine machine or you must be doing something wrong (likely broken/missing distro packages).
Since you didn't state the Wine version nor provided (attached) any backtrace/terminal output there is nothing to do.
$ wine --version wine-1.7.21-19-g8812193
Regards
