I am running MS Office 2010 and Windows 8. I installed the full Office 2013 (not the demo) and decided I didn't like it. Uninstalled it using the FixIt tool. Everything uninstalled fine with the exception of a minor problem in Outlook. When I start outlook (2010), I get a pop-up window that reads: There is no email program associated to perform the requested action. Please install an email program, or if one is already installed, create an association in the Default Programs control area. If I click Okay, the box goes away, and the Outlook program functions fine. I imagine the problem has to do with some sort of configuration 2013 did with outlook.com or something, but I don't know how to disable that association (if that's the problem). Would appreciate some help. Thanks.
