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.

I will look into this for the next version of Driver Sweeper, I'll make sure that the restore of Driver Sweeper will be able to restore all the files and directories. Driver Sweeper always has backups of all files and directories, if it's not possible to create a backup the file/directory is not deleted.
Portanto, parece que alguns arquivos não podem ser restaurados pelo usuário ou pelo programa (no momento)
