I was getting this message after buying a new computer. Windows 7 HomePremium, plus Office 2007.
I'm not sure why it happened I eventually found that the files I'd imported had the Solver Add-In disabled. The box was ticked in Excel Options but it didn't show upon the Visual Basic Button in the Developer Tab.
Unchecking the Solver add in and re-checking it solved my issue. Still no idea why it happened though.
