Correct.  UAC Installer Detection Technology applies only to 32bit
executables; without that patch, setup64.exe would not elevate
automatically, which we believe would run contrary to what most users
are expecting.

I have partially reverted that change, so that your renaming
circumvention will still work with setup.exe (32bit); if you want this
to work with setup64.exe (64bit), I'm afraid you will need to build it
yourself.
