  Hello

  You are unable to download the updates?

  Try the following steps to resolve the problem:

  Method 1: Temporarily disable any security (including firewalls) software and check if the problem persists.

  Check out these links:
  http://Windows.Microsoft.com/en-us/Windows7/turn-Windows-Firewall-on-or-off

  http://Windows.Microsoft.com/en-us/Windows7/disable-antivirus-software

  If disabling the security software solves the problem, then contact the manufacturer of the specific security software to fix the problem.

  Important: 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 not disable temporarily to install other software, you must reactivate as soon as you are finished. If you are
  connected to the Internet or a network during the time that your antivirus software is disabled, your computer is vulnerable to attacks.

  Method 2:
  See the article mentioned below and run the Fixit diagnostic tool to fix the error 643.
