I have an Acer Aspire 5349-2899 with Windows 7 (64 bit) that I purchased in June. The first time I turned the computer on it was fine and I was just exploring how Windows 7 works, since I am not familiar with it, about 5 minutes. Yesterday I turned it on and installed Microsoft Essentials with no problem. Tried to install Microsoft Office 2007 and received Error 1935. An error occurred during the installation of assembly component {837BF1EB-D770-94EB-A01F-C8B3B9A1E18E}, HRESULT: 0X800736fd. Not sure what that means but I decided maybe I needed windows updates and received error code 80090005 after about 3 hours of running. I did call Acer this morning and they told me that error code 80090005 was a security issue but would not help without paying them. What is the best solution, should I do a restore, if that is the case, how? Thank you
