currently we are using the instructions on http://blogs.technet.com/b/odsupport/archive/2011/04/06/how-to-perform-an-uninstall-upgrade-to-office-2010.aspx
to upgrade our office to 2010. We currently have both xp and windows 7 computers and it is a mix of office 2003 and 2007 here. Windows 7 computers work fine, we reboot them, the script runs, office 2007 is uninstalled and 2010 is installed. For XP however, regardless of the office versions, we reboot them, the script runs, office 2003 is uninstalled but 2010 is not installed unless we reboot again.
Is there something we are missing on this script for XP computers? Our group policy is off of a windows 2008 server
