http://appdb.winehq.org/objectManager.php?sClass=version&iId=17336 In the howto for Pro + (wine w/o wine-mono support) step two: Delete all .NET-related registry keys. How does one go about doing that ? $ regedit --> Find --> .NET and go willy nilly on the registry ? Or look for a folder in HKEY_LOCAL_MACHINE ? Sorry if this is something obvious but I have no clue. Skimmed FAQ/Wiki/etc. but all I saw was how to use regedit but not how to delete all "blank"-related keys Any help would be greatly appreciated.
