Windows 7 plus Driver Sweeper equals BIG PROBLEM with Windows 7 SP1
Heads up everyone that has used "Driver Sweeper" to clean up ATI drivers from your Windows 7 system.
http://forum.phyxion.net/viewtopic.php?id=17If you run Windows 7 and have ever used a program called "Driver Sweeper" to clean up a problem with your ATI (AMD) video card driver installation, you may be in for a big surprise when you attempt to install Windows 7 SP1 when it is released in a few days.
Apparently Driver Sweeper deletes (cleans up) entries and files for ATI video drivers that are actually part of the original Windows 7 install package. When you attempt to install Win 7 SP1, the installer finds that these entries and files are missing and fails with an error code 0x800f0a13.
The Author of Driver Sweeper has released a fix for this problem and it can be found here.
