Why?  The idea is that setup is called, performs a CopyFile of itself
and then exec's its copy.  If the copyfile fails with a sharing
violation or something like that, the copy is in use, which means, setup
is already running.  However, if the copy already exists and can be
overwritten. it's just some older copy.  I don't think there's a
necessity to remove the copy at all.

I like the idea in genral, but I'd also like to write SHTDI in all
uppercase.  Well, it already is, but you get my meaning...
