I'm not a developer, but it appears that you might be able to make
TurboCASH function on Linux with Wine if you go about it in a slightly
different way.... Here's my suggestion:
Most of the time with Win32 apps on Wine, you don't have access to the
source, so all you can do is run the binary/installer with Wine, and
hope that it works. I noticed that TurboCASH does seem to run on Wine,
but unfortunately requires native Win32 DLL's, which require a valid
Windows license.
However, since TurboCASH is open source, the options are a bit greater.
If you have access to the source, you can run it through winemaker,
and it appears that it will let you create a Linux version of Windows
code with relative ease. Winelib is specially designed for developers
who have Win32 code that they want to port to Windows. The result will
still depend on Wine to run, but it appears that it might work better
than trying to run the regular Win32 compiled binary with Wine.
I may be dead wrong, or you may have already considered this, but I
thought I'd at least mention it. Here's a few link to the process of
porting Win32 code to Wine via Winelib:

Any thoughts on this? Thanks!
