I've been deploying GroupWise via GPO to Windows since version 6 with no problems until now. GroupWise 7.03 installed just fine with this method and GroupWise 8.01 installs fine to Windows XP systems. However when deploying to Windows Vista or Windows 7 I get the following 2 errors in the Event Viewer
