Setup has encountered an error and cannot continue. Contact Adobe Customer Support for assistance

Trying to install CS4 Design Premium onto Windows 7 Ultimate 32bit. When I click on Setup.exe it begins to install saying "Checking system profile." then after about 15 seconds the error pops up. "Setup has encountered an error and cannot continue. Contact Adobe Customer Support for assistance." When I contact customer support, of course they tell me to check here. Unfortunately the error is so generic that it is difficult to do a google search. Any help would be great.
