When i open Word or Excel i get a "microsoft forms" message window stating "could not load an object because it is not available on this machine". I click on it once and it goes away and another one appears. I click on that one and then the document opens. I have Excel and Word 2007 pre-installed on a lenovo T400 with vista business 64. I have had this computer over a year and this started happening a few months ago. I think it has something to do with an error with an Ad-In.
