Cannot Re-Install CS4

I updated my hw and cannot get CS4 to re-install. 

New machine running Win7 (64bit).  I have removed adobe reader and the flash player.  I then ran "the cleaner".

It appears to want to load then "Critical errors were found in setup..." OK it exits. 

I have been try to do this simple install, for nearly 3 hours.

Suggestions (besides spend another couple grand?) 

Thanks,

TM
