It's not, indeed. Having used setup regularly (to C:\cygwin64), I once
installed a second one (C:\cygwintest) and setup got stuck to that
directory, despite later updates to C:\cygwin64. Happened on more than
one machine. However, I did also use older versions of setup in various
combinations, like to C:\cygwin32 or C:\cygwinxp64. Maybe those older
versions are getting sticky in the registry in a way that confuses
current setup?

Thanks, I'll do that.
