I believe you.

Again, I believe you.  You've already gotten a couple suggestions on
how to detect Wine, which you may use.  We just don't recommend that,
as the methods may not be supported in the future.  Whether you choose
to heed my recommendation is up to you ;-)

Still, it'd help if you could log a bug about it.  Include which
software it is, whether and where a copy is available, how network
drives are mapped, and so on.  Without a good bug report, we're rather
less likely to fix it.

Out of curiosity, is the previous installation likely to be found
under Z: ("/") rather than under C:?
