The .NET Framework setup team has released an updated version of the .NET Framework Repair Tool that adds support for diagnosing and repairing issues with .NET Framework 4.5 and 4.5.1.  This repair tool can identify and fix issues with the installation of MSI-based versions of the .NET Framework, but it cannot fix issues related to versions of the .NET Framework that are installed as a part of Windows.

If you run into installation issues with the MSI-based versions of the .NET Framework 2.0 SP2, 3.0 SP2, 3.5 SP1, 4, 4.5 or 4.5.1, I strongly encourage you to download the .NET Framework Repair Tool and run it to see if it resolves your issue before resorting to trying the .NET Framework cleanup tool. Here are links that you can use to find additional information about the .NET Framework Repair Tool:

  • Hey,Your content is just so wonderful regarding the updated version of .NET Framework. I went through your blog when I was searching for .Net Framework in Google.I must say your blog is so mush helpful.

  • Hi Aaron,

    I have used both of these on occasion for years, Thank You for the heads up. I don't need them right now but I am now on W 8.1.1 Pro.

    The question is, how will they both work on my current OS? I don't see anything beyond W 7 or W 8.0.

    Best Regards,


  • Hi Phantom of the Mobile - The .NET Framework Repair Tool only fixes issues with redistributable versions of the .NET Framework 2.0 SP2 or higher.  On Windows 8.1, the only versions of the .NET Framework 2.0 or higher that are possible to install are OS components and you can't install the redistributable versions on Windows 8.1.  As a result, there currently isn't any value in running the .NET Framework Repair Tool on Windows 8.1.
