Trying to upgrade to Windows 7 from Vista - error code 0x7E
I have a Compaq computer w/Vista Home Premium, 32-bit. I'm trying to install the Windows 7 Home Premium upgrade because my Office Professional 2007 disc will not load. I'm getting error code 0x7E: The file 'autorun.dll' could not be loaded or is corrupt.
Setup cannot continue. I'm getting very frustrated with Vista!! Please help!

2. Disable all security software including anti-virus and firewall programs.
Make sure you enable the anti-virus later

4. Disconnect all external devices except keyboard and mouse before installing.
5. If your computer/motherboard has integrated video use that and remove the dedicated video card.
