[Wine] Wine can't find c drive!

[kh2reed]

Hi,
I am trying to run a game (Touhou 7) on a mac using wine.  I installed wine using macports and used the command $ wine $th07e.exe to run my installer
it then gives me this message:

wine: cannot find L"C:\\windows\\system32\\.exe"

I read elsewhere that i should type winecfg and create a fake c drive.  But when I look in my drives menu, there is already one labeled c.  Why can't it use this?  I might be missing information, if I am, I will provide it.
