Error Code: 0x8E5E03FA (Can't install SP1)

I cannot locate what this error code means, but I got it when trying to install Windows 7 32-bit Service Pack 1. I have done everything suggested at Microsoft's site to ready my computer for installation of it, and it got farther (about 70% this time) than before, but it still won't install. I can't correct the problem if I don't know what it is. I have used Microsoft's Troubleshooter and problem identifier, and it fixed some issues, but obviously not all.

Temporarily disable or uninstall your security software 


Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you are connected to the Internet or a network during the time your antivirus software is disabled, your computer is vulnerable to attacks.
