automated / unattended UNINSTALL - Solidworks 2006

Hey everyone, my company is getting ready to move to SW 2008and we're looking for a way to automaticallyuninstall Solidworks 2006. I've created a Group Policycomputer startup script that uninstalls PDMWorks, eDrawings(several versions), and Solidworks in that order but Solidworksdoes not uninstall.

I've tried logging the uninstall using the msiexec uninstallfeature but it does not tell me anything useful.

HOWEVER, if I log is as a domain admin and run my script manually,everything works just fine...

Any help you all can provide would be great, thanks inadvance.SolidworksAdministration
