This is the worst piece of software I have ever used. Before I even use it. It does not accept the product key provided in the box (ordered from amazon). I have tried virtually every possible misprint/mispelling of the product key... but the product key seems to be easy enough to read to me... Microsoft's site has no support number listed. Microsoft assigns you installation a unique number, then does not accept it for help on the support site. Office 2011, you are a steaming pile of crap, and it will be a cold day in hell before I buy another Microsoft product. Death to microsoft!
