VISIO 2010 keeps configuring

Have been struggling with this for days so help appreciated. Originally, XP SP3 machine with Office 2007 Pro installed. Then installed VISIO 2007 Pro. Installed fine, but then when running, every time went into "configuring" before eventually launching. This was using a domain account which has domain admin rights and is a member of local admins. If I log in as local administrator account (or a separate local account which has been made a member of local admins), it launches without an issue. Then installed Office 2010 (into different directory) and VISIO 2010 - same issue. Stripped off all Office applications and ran the two "FIXITs" for Office 2007/2010. Rebooted. Ran install of Office 2010 - fine. Ran install of VISIO 2010 - same issue. Tried using both the norereg and subinacl "fixes" and fixing the defltbase file - all to no avail. Ran regmon to compare working (local admin) launch with non-working (domain admin) launch to see if could capture differences, but there are just too many differences to go through.

Suspect this is a bug in the install for VISIO 2010 which does not assign correct permissions to a registry key or file somewhere, but checked the Microsoft site for hotfixes - nothing. Many people complaining of same issue with other Office 2010 and 2007 applications, but most are fixed using the actions suggested here :-

I have tried all of these actions, the permissions seem correct and running an effective permissions on the areas shown for the domain account does indeed show that it has full control.

Help please before this drives me to jump into the nearest boyne !!
