Duet Client Installation Fails Due to .NET Installation/Upgrade Failure


Attempting to install the Duet Client results in the following .NET installation Error in the %temp%\dd_dotnetfx20error.txt log file

“Error: Installation failed for component Microsoft .NET Framework 2.0a. MSI returned error code 1603”



The .NET framework installation has gotten into an unmanageable state (e.g. can’t be upgraded, repaired and/or uninstalled)



You will need to resolve this before continuing the duet installation. Please use the “.NET Framework Cleanup Tool” to cleanup the previous .NET installation. The tool along with detailed instruction on using it can be found at the following blog post.
