Having trouble with your .NET framework? I had a difficult time getting Windows Update to install Hotfix KB928366 on my computer. No matter what I did, I couldn’t uninstall or fix the .NET Framework. After a lot of Googling and trying different suggestions, here is what worked for me.
How to re-install the .NET Framework 1.1
- Remove the .NET Framework 1.1
- Download the Microsoft Windows Installer Cleanup Utility and install it.
- Run it from Start > All Programs > Windows Installer Clean Up
- Select .NET Framework 1.1 from the list and click Remove
- Download and install the .NET Framework 1.1 Redistributable
- Download and install .NET Framework 1.1 Service Pack 1. Ignore the message saying it is already installed, go ahead and reinstall it.
- Download and install .NET Framework 1.1 SP1 Security Update (KB928366). Reboot when asked to.
If this doesn’t work for you, here are additional instructions for repairing .NET version 1.1, 2.0 and 3.0.
Repair .NET Framework 1.1 (method 2)

- The msizap.exe utility in step 4 of the article is included in the Windows Installer Software Development Kit for XP and Vista. During installation, select not to install the documentation and samples to avoid downloading 1GB of unnecessary files. (I selected only Visual C++ Compilers and Win32 and .NET Development Tools which came to 32MB)

Repair .NET Framework 3.0
- Unfortunately there does not appear to be any particular article pertaining to .NET Framework 3.0. I have not had issues with this version, however just going into the Control Panel > Add or Remove Programs and locating and removing it and its patches should be enough to get rid of it. I suggest you do the same and then reboot…
- Download and re-install using this distributable package:
