I hope that by "ProgramW3264dir" it doesn't refer to the WOW64
thing. That's how 64-bit Windows runs 32-bit programs, if I'm not
mistaken. If it needs that you would have to do the complicated WOW64 WINE
setup.
Maybe it simply is missing that registry key. I'd try installing into
Windows, opening the registry editor, hit ctrl+f, and search for
"ProgramW6432dir" and see how many they are. Export the keys to *.reg
files, put them somewhere Linux or Mac or whatever can see them (like a thumb
drive or if the NTFS partition is visible, that's fine), go into Linux or
Mac or whatever, open the WINE registry editor, and import those *.reg files.
I'm not saying that would work; I'm just saying that's what I
personally would try.
Cheers,
Jake
