Windows 10: Failure to execute an update to a 3rd Party Program

I'm having a 3rd party software GTPro 31 by Thermoflow installed on my laptop that is using Windows 10. I used to install new updates for the program successfully. However, recently I can't update the program as I receive the following message when running the update installer:Windows Installer: "The installation source for this product is not available. Verify that the source exists and that you can access it."I can't think of any change that I did recently except updating Windows to Version 22H2 OS Build 19045.4651Appreciate your support,Yasser

3rd party AV program

The message you are describing may be observed if another antivirus program is still installed or there are remnants of a third party antivirus program still installed.

Note the statement "If you want to use Windows Defender Antivirus, uninstall all of your other antivirus programs and Windows Defender Antivirus will automatically turn on. You may be asked to restart your device."

Go to Security and Maintenance, look in 'Security' and see what program is listed under Virus Protection. Windows Defender will not be enabled and functioning properly if there is a program other than Windows Defender listed.

You may want to try the steps recommended in Problems
starting Windows Defender in Windows 8/8.1/10 to include running SFC, scanning for malware with Malwarebytes and running the software removal tools for any security software (Avast,
AVG, McAfee, Norton, whatever) that may have previously been on the computer followed by a reboot? List of
anti-malware product removal tools

And see Configure Windows Defender in Windows
