------- Additional Comments From ben@atomnet.co.uk 2007-15-02 15:22 ------- Found the problem. I ran wineprefixcreate with a new version and saw:
err:ole:TLB_ReadTypeLib Loading of typelib L"c:\windows\system32\msi.dll" failed with error 1813
Seems something had installed an msi.dll and even though it wasn't set up to be an override it was still being used anyway. I'm not sure what to do about this bug, obviously deleting the bad .dll fixes it but it shouldn't have been used in the first place...
