AMD Catalyst Software - Does not install, it extracts!

[HoppaLong]

XP Pro_SP3

Guys, I'm going a little crazy. I need a working copy of Catalyst Control Center, but something
is messed up with these installers.

I've got three versions of AMD Catalyst Software with release notes. The release notes
are important because many sites list their versions of Catalyst as compatible with XP.
Most are not. The AMD release notes for all versions list the compatible operating systems.

The last version I attempted to install (12.4) extracted the files in their folders. Nothing is
installed. The same thing happened with the other two versions I downloaded.

If I run "Setup.exe" the installer just starts the same process over again. Nothing is installed.

I've never seen anything like this before. Why is this happening and is there a solution?
