wine users - Jul 2011 - Re: Uninstall Windows Apps?

[...] Was the WINEPREFIX environment variable set?  [...]

I didn't set it explicitly. How can I check?

[...] Also I would avoid using the root user in wine. [...]

I agree 100%. I only did it as test.

Would an "echo WINEPREFIX" in terminal tell you? I'm away from
Linux at the moment, so I can't check at the moment.
