Office 2010 always reconfiguring itself on startup

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?


OK, have had a little bit of a hunt...

MS Answers recommend the following suggestions:

  • Peform a "repair" on your Windows installation and the Office installation (although in the context of the linked discussion they were talking about Windows 7, not XP).

  • Re-install Office (including hints about how to remove Office completely first).

  • Check you don't have multiple version of Office installed.


There are a number of other forums with similar problems. The issue I had seems to be registry related.

Others have solved the problem by completely removing previous versions of Office using the Office clean up process and reinstalling. The thread that @DMA57361 pointed to contains the full story.

In my case, I suspect some registry permissions were not left in a state that Office 2010 was expecting (e.g. non-admins not having Read access).

The solution is available here.

Looking into the Event Viewer after a failed startup gave me a list of events for the MsiInstaller. Messages 1001 and 1004 gave specifics about which registry keys were causing the problem. In the cases listed, it seems to be to do with the permissions on the various file type keys e.g. HKLM/Software/Classes/.msg. Giving non-admin users read access to these keys, sub-keys and values and ensuring that they are owned by an Administrator fixed the problem.

Note: The real answer is to rebuild the box and reinstall the OS too. Too many interactions between Office and Windows registry components.


I know this is an old post but I had the configuration issue for days and did not find an answer that worked for me so I would like to offer my experience in case there is someone like me looking for an answer.

I installed office 2007 pro and visio 2007 pro on a new 64 bit windows 7 system. It was all working fine for a few weeks. I then had the opportunity to install office 2013 pro (for $10 thorough job). I installed it and kept 2007 since 2013 did not include Visio and I use it a lot.

Few days later I needed to have Acrobat pro and so I installed my old copy of Adobe CS3.

Not long after I noticed the issue with configuration running every time Visio (and only Visio) started. Annoying as heck because it would run even if I had one instance running already and opened another with a different drawing!

After days looking for an answer I decided it had something to do with the Adobe add-ins running on Visio.

Solution - uninstalled both visio and adobe. Reinstalled Adobe first and got updates (had to reset system clock to Oct 1, 2011 to get updates!?)

Restarted and then reinstalled Visio. Voila! Everything working beautifully :)

Hope this helps someone!
