Problem W/SolidWorks and Vista

I loaded SolidWorks on my new home computer and it loadedokay. At the end of the install I was able to open it. After Iclosed it the first time, it won't open. It says
"a problem caused the program to stop working correctly." themessage in the Installation manager states "the current operatingsystem (ID#32) is not supported by the Istallation manager. Youmust download and install files manually." Any Idea's how I can getthis working? any info will be helpfull.

Thanks,SolidworksGeneral
