Microsoft Net Framework 1.1 Service Pack 1 won't update

jimimi

I'm trying to update my old laptop (Windows XP Media Centre Edition 2005) but the above won't update. It says failed. I seem to remember it doing it before when I've tried too. Is it an important update, and if so, what shall I do?

Thanks, Sam

I've had problems with other versions.

I eventually fixed it by uninstalling all versions of .Net, run CCleaner - both files & registry, reboot and go into Windows Update and install all of it's suggestions one at a time.

Repair the .NET Framework
To repair the .NET Framework, you must uninstall multiple versions of the .NET Framework by using the .NET Framework Cleanup Tool, and then reinstall the components.

To do this, follow these steps:
Click the following link to download the .NET Framework Cleanup Tool:

Use the .NET Framework Cleanup Tool to uninstall the .NET Framework versions 1.0, 1.1, 2.0, 3.0, and 3.5
Note The cleanup tool does not let you remove the .NET Framework 2.0 in Windows Vista or later versions because the .NET Framework is installed as an operating system component.
Restart the computer.
