Well, is it possible to use 7zip? It seems like you can do something like it in: https://superuser.com/questions/42788/is-it-possible-to-execute-a-file-after-extraction-from-a-7-zip-self-extracting-a
Not that I think this would help with heuristics, and some AV tools REALLY don't like executing things from users' temp directories. (Which .Net applications seem to like to do sometimes.) Maybe have compressed and uncompressed installers?

NOW I > can update Cygwin... I wonder if UPX compression of setup makes as much sense now as it did 20+ years ago. Not only does it (occasionally) generate problems like this, but also with malware detection heuristics. OTOH, not using it would make setup ~4x larger. ::DISCLAIMER:: ________________________________ The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.
