[Wine] Help With My Little Project

[MechaRocks]

Ok, I am trying to make a mac version of my friends windows program.  Now, this exe file needs another exe file in the same folder as the main one.  I tried installing the main one into wine, but when I run it, it keeps telling me that the other file is missing, so I put the other file in the same folder (with show package contents) and it still gives me the same error.  Does anyone know how I can solve this?
