Hmm.. interesting.. Winamp installs the media library into C:\Users[user name]\AppData\Roaming\Winamp on Windows 7 Ultimate 64 bit and it works just fine. Is there a parameter for Wine when installing a windows app to make the windows installer think it's windows 7 that it's installing on to?
'wine winecfg', change windows version to Windows 7.
