  • Hi Titaniatic,

    According to the error you provided, it could be related to the .net framework files. Please check the link below to use the commands to repair the files.

    Please Note: Since the website is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.

    If the issue still insists, I suggest that we could remove and reinstall the .NET 3.5 and then the service pack from Microsoft Download Center:

    Please Note: If we try to remove .NET Framework, we could also use the cleanup tool in the link below.

    Hope it will be helpful to you

  • Can you explain more about the error that you have experienced.

    Were there any error codes?

    Were there any error messages?

    After a clean install of windows 10 version 1703 I attempted to install Intel software that kept displaying Net Framework errors. 

    Scannow and restorehealth displayed no integrity violations and / or completed successfully.

    Intel did not know how to troubleshoot the problem other than attempting to reinstall Net Framework.  When this was done there was an error message "your installation will not occur" indicating that net framework 4.6 or greater was already installed on the computer.

    If you are considering removal and reinstallation of net framework you should consider trying this administrative command prompt to see if it can fix your problem:    lodctr /R

    The letter R must be capitalized and it took several attempts to get the command to work.

    It fixed the problems that I had had and the Intel software was able to be installed.  The Net Framework error no longer occurred.  The software works fine now after the command.
