In trying to look/install some missing files, I went to use my Windows 7 Home disk for repair. It would not work. Instead I got the following message: "Autorun.dll could not be loaded or is corrupt. Setup cannot continue. Error code is [OX7E].". I received the same message when I tried install MS Office 2010. As a side note, I've been unsuccessful in several install attempts of the Windows 7 SP Pack 1. Any suggestions?
