This is generated by a problematic program in windows. Check your event viewer and it should tell you the program causing the error. You can also check out microsofts website.

You can go to:The requested look up key was not found in any activation context - MSDN Forums (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1122973&SiteID=1)

I hope this helps you.
