Hi Steve,

I've got the same problem as you mention in your Office 2003 post re the apps running Windows Installer multiple times on startup and that you fixed it by granting permission to HKEY_CLASSES_ROOT\Software\Microsoft\MasterAggregatorForIPP\MSDAIPP so I've tried to grant access to everyone so they can write to this key. I'm still getting the error messages though. Any suggestions?
