I recently obtained two Microsoft programs as a gratuity for participating in a Microsoft development project. 1) Microsoft Office Professional 2007 and 2)Microsoft Flight Simulator. When I try to load either one, I get an error message. i.e. (for Office) I get; ""Error 1935 An error occurred during installation of assembly component {97E81AF1-0E47-DC99-A01F-C8B3B9A1E18E}, HRESULT: Ox800736FU."" When I try to load the Flight Simulator I get, again, "Error 1935" But with a different string of alphanumerical characters. I am using a HP Pavilion, with 2 GB ram, 200 GB hard drive and Vista OS. What really ticks me off is that, before I tried to load Office 2007, I unistalled Office 2000 that I had been using and I cannor reinstall it. Now I am stuck with no WORD or EXCEL. Can any one help. Thanks for listening (reading) to my troubles, JIM
