what all this means and few probably do, but at least it does state that it run on a 32 bit platform, which is a start ;) Just make the process clear, I've removed all wine packages and dependencies. I've reinstalled wine and wine_gecko. Configured with # WINEARCH=win32 winecfg And that's about it edit: oddly enough, after doing # wine /Download/calypso.exe &> winelog.txt The previously posted crash does not occur? How is that?
