I have a problem and I wonder whether someone can help me. This morning Microsoft downloaded quite a few updates. One of them did not install. It is the one below: --------------------------------- Microsoft .NET Framework 1.1 Service Pack 1 Security Update for Windows 2000, Windows XP, Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2 (KB953297) Installation date: 14/10/2009 1:17 PM Installation status: Failed Error details: Code 643 Update type: Important A security issue has been identified that could allow an unauthenticated remote attacker to compromise your system and gain control over it. You can help protect your system by installing this update from Microsoft. After you install this update, you may have to restart your system. -------------------- As you can see, the installation failed. I cannot find what code 643 is all about and what I can do to instal this update. Can someone help me please.
