    For third party applications contact the company for support.

    Other options for application problems are:

    a) placing the computer into clean boot:

    b) run the program compatibility troubleshooter:
    Open administrative command prompt and copy and paste:
    msdt.exe -id PCWDiagnostic

    Click view detailed results.

    Post images or share links displaying the results.

    For share links use one drive, drop box, or google drive.

    Consider making free backup images so that at any time you can restore an image:

    (Acronis, Aoemi, EaseUS, Macrium, Paragon)

    A windows 10 license can be upgraded to windows 11 for free.

    To downgrade perform a custom install or clean install with a Windows 10 iso.
