I did a Change to my Office 2007 install through the Control Panel and saw that Outlook 2007 had been turned off. I reset it to run from my computer and it reinstalled itself. The only problem after that was the profile had been changed by Outlook 2010 and caused some problems in Outlook 2007. I had to create a new profile but I was able to recover all of my emails and used the opportunity to clean up my email handling some.
