Method 2:
I would suggest that you place the computer in the Clean Boot state and check if it helps.
To help troubleshoot error messages and other issues, you can start Windows XP by using a minimal set of drivers and startup programs. This kind of startup is known as a "Clean Boot." A Clean Boot helps eliminate software conflicts.

Method 3:
Try downloading the update manually.

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