Microsoft .NET Framework Repair Tool

Corrine · Jun 26, 2012

Anyone who has ever had a problem with .NET Framework, particularly a repeatedly offered security update, knows how difficult it can be to fix. Without a specific error code, it is more difficult to research the source of the problem.

Until recently, the primary go-to source for help was Aaron Stebner's WebLog on MSDN Blogs at Unified .NET Framework Troubleshooting Guide. I have also provided the recommendation to install .NET Framework security updates, with a shutdown/restart and separately from other security updates.

Troubleshooting .NET Framework problems may be near an end with the release by Microsoft of the Microsoft .NET Framework Repair Tool. As described in Microsoft KB Article 2698555,

The tool may make one or more of several possible changes to the installed product. For example, it may correct the state of Windows Installer on the computer, reset the DACLs on certain folders, or resolve some issues that are related to invalid or corrupted update registration.

The tool follows a four-step process:

Try to troubleshoot the issue.

Apply the fixes (with user consent).

Try to repair the .NET Framework 4.

Collect logs (with user consent).

By the way, users of SysInternals Process Explorer may be interested in the description of the New .NET Diagnostic info added to Process Explorer in the MSDN .NET Blog by Brandon Bray.

I will be very interested to see how well this works. Thanks for posting this, Corrine :)

Microsoft said:
Note: The current version of the tool supports repairing the .NET Framework 4, this will be extended to include other versions of the .NET Framework in the future.

Hopefully it will be extended soon. It sound extremely useful.

Indeed, niemiro, it seems I've seen more issues with .NET Framework 3. So, until expanded, stick with Aaron Stebner's helpful information!

Another useful tool (aside from his Unified .NET Framework Troubleshooting Guide) is Aaron Stebner's .NET Framework setup verification tool. It is designed to automatically perform a set of steps to verify the installation state of one or more versions of the .NET Framework on a computer. More information and download link at .NET Framework Setup Verification Tool User's Guide.
