Hi, I have an HP desktop and am doing a vista clean install using a retail disc. After formatting the drive during the install, I got a message that says: Windows cannot install required files. Make sure all the files required for installation are available, and restart the installation. Error Code 0x8007045D. Does anyone know how to solve this problem? I made my vista disc from here http://www.mydigitallife.net/2007/12/22/64-bit-x64-windows-vista-official-direct-download-links/ Thanks!
