I have posted an updated version of the .NET Framework cleanup tool that now contains support for automatically cleaning up the .NET Framework 1.0, the .NET Framework 1.1, the .NET Framework 2.0, the .NET Framework 3.0 and the .NET Framework 3.5.
This tool automates the manual cleanup steps for the .NET Framework 2.0 that I posted a while ago. These steps have helped solve most of the known .NET Framework 2.0 beta uninstall issues that I know of. In addition, the tool can be useful to return your system to a known (relatively clean) state in case you run into any .NET Framework 2.0 installation failures so that you can try to install again.
The updated version of the cleanup tool contains options to clean up the .NET Framework 1.0, 1.1, 2.0, 3.0 and 3.5 separately and all versions simultaneously in a single step. The cleanup tool contains logic so that if it is run on an OS version that includes the .NET Framework as an OS component, it will not offer the option to clean it up. This means that running the cleanup tool on Windows XP Media Center Edition or Tablet PC Edition will not offer the option to clean up the .NET Framework 1.0, running it on Windows Server 2003 will not offer the option to clean up the .NET Framework 1.1 and running it on Windows Vista will not offer the option to clean up the .NET Framework 2.0 or the .NET Framework 3.0.
There are a couple of very important caveats that you should read before using this tool to cleanup .NET Framework bits on your machine:
- This tool is designed as a last resort for cases where install, uninstall or repair did not succeed for unusual reasons. It is not intended as a substitute for the standard uninstall procedure. You should try to perform an uninstall from Add/Remove Programs before using this cleanup tool.
- This cleanup tool will delete shared files and registry keys used by other versions of the .NET Framework. If you run the cleanup tool, you will need to perform a repair or reinstall for all other versions of the .NET Framework that are on your computer to get them to work correctly afterwards.
I have been using this tool for a while, and it has proven reliable, but there may still be bugs in it in certain scenarios. Please contact me if you run into any issues while using the cleanup tool or if you are still unable to install the .NET Framework (or any service packs or hotfixes) after running it.
The tool has a command line switch that allows it to be run in silent mode if needed. There is more information about how to run it in silent mode in the .NET Framework Cleanup Tool User's Guide.
