Norton System Works

If you are running Windows ME and have Norton System Doctor installed, search your system for files called OEM****.INF (where * is variable) and the files are zero byte in size. If you find them delete them, turn off System Doctor and try the install again.

Microsoft have issued a patch that will resolve this issue - see the link below:

CreateFile Improperly Returns ERROR_ALREADY_EXISTS if the Drive Is Locked and the File Did Not Exist

Another problem caused by this programme is:

Norton System Works 2000 Is Not Compatible with Windows Millennium Edition (Q290664)

The error mentioned (Windows could not update the file %1 from %2) can occur when rebooting after an IE upgrade or install, or when doing a normal reboot in WindowsME.
