    Hi, thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today.

    I understand the issue you have, there is nothing to worry I am here to help, this is an issue with misconfigured .Net framework on the PC and for us to sort out the issue kindly follow the steps below:

    Method 1. Download and Repair .Net Framework.

    Kindly download and repair the Framework using this link: https://www.microsoft.com/en-us/download/detail...

    Once done downloading and running, try restarting the device and check.

    Method 2. Uninstall and reinstall .Net framework

    Press the Windows key + R then type in:

    optionalfeatures

    Then hit OK

    uncheck for .Net framework 3.5 then follow the prompt and restart PC.

    Once the PC is booted again.

    Press the Windows key + R then type in:

    optionalfeatures

    Then hit OK

    Click on Turn Windows Features on or off

    check for .Net framework 3.5 then follow the prompt and restart PC.

    If none will work from the above solution, I suggest doing an in-place upgrade wherein it will upgrade the device to the latest version and repair all issues without deleting any files.
