Help. I'm running Windows XP and have Microsoft Office Small Business 2007. I've been running this for several months now with no issue. A few days ago, I went to check my Outlook and received this message 'Microsoft Office Outlook has not been installed for the current user'. I am the only user. And, all of my other MS Office programs (Excel, PowerPoint, etc) are giving me the same error. I have researched resolutions and none have worked (clearing registration key, removing and reinstalling, repair). Could someone please help me and tell me how I can get rid of this crazy error and open my Outlook? Thanks.
