If there is a "glitch" (or bug) in setup, we'd like to know about it (and
fix it), no matter what precipitates it.  IOW, did you use "setup.exe" to
download the files for your local mirror?  If so, zlib should have been
selected.  If not, and you simply didn't download zlib, you may have other
problems later with missing dependences that lurk on your system.

Is there a tool that would do that, or does it require registry hacking?
The reason I'm asking is that if there is a tool, people might have run
it, and we should then add an entry to the FAQ with something like "my app
just doesn't work with no apparent output" as the question, and the
answer pointing them to the event log...
