I've just installed Office 2010 Professional Plus (upgrading from Office 2007). It works fine under my admin account, but when I login with my wifes non-admin account, every time I open a document or start an app (Word, Excel, Publisher ...) Office 2010 goes through its configuration process (starting the the standard install dialog and then running the bootstrap process) before it loads the app - which wastes 2-3 minutes.

Once it's done this, the app runs fine and I can make setting changes that are remembered when it restarts, but I can't work out why it thinks it needs to configure the app each time.

Any thoughts?
