2009 Installation on Vista Business 64bit

I am installing SolidWorks 2009 SP0 from DVD on my computerrunning Vista Business 64bit. I started an installation and got themessage below. I figured I might have something running in thebackground so I restarted my computer, restarted the install, and Istill get this message. I get it two times during the install...atabout 10% and again at about 90%. I say ok and installationcontinues, but I get an uneasy feeling when this happens.

"The Installation Manager has detected that SolidWorks applicationsare running. You should exit these applications before continuing"

Anybody else seen this? See attached...SolidworksAdministration
