MS OFfice 2003 worked fine the other day. Today, when it launches, it opens completely. But when I go to open a file, the install wizard pops on. It gives me a message error 25090 sysetem error 2147023838 and some mumbo jumbo about reading the Office Source Engine which is not helpful.

I tried setting all the property permissions, but even as an admin, there seems to be a missing security tab. I have no clue how these settings got changed since I'm the only one on the computer.

I don't want to have to reinstall ms word 2003. Could a registry checker have deleted something or a defrag files done something?
