Steps to repair the .NET Framework installation

  1. Obtain the original installation source. For example, if you installed the .NET Framework from a CD-ROM or from a DVD, insert that disc. If you downloaded the .NET Framework , download the .NET Framework again. Make sure that you click save to disk. If you installed the .NET Framework from a network share, reconnect to that share.
  2. Click Start, click Run, type the following command, and then click OK:
    N:\dotnetframework\dotnetfx.exe /t:c:\temp /c:"msiexec.exe /i c:\temp\netfx.msi REINSTALL=ALL ReinstallMODE=vomus"
    Note Replace N:\ in this command syntax with the original installation path.

    Important If you do not have a C:\temp folder on your computer, create one before you run this command.
The Microsoft Windows Installer will verify and repair the .NET Framework installation.
