    I solved the problem.
    The problem arises if windows (for some reason) “do not automatically update root certificates”. This has many other issues.
    1. Download https://www.digicert.com/util/ digicert certificate utility for windows
    2. Run the utility and from the menu select “tools” and then AutoRootUpdate.
    3. Change the setting to ‘Disabled’ . (Yes ‘Disabled’). Problem solved

Hi Ash,

Thanks for the reference to the MS error code.  After ensuring that the time on the remote PC was correct, we ran a SFC /scannow on it (recommendation from the MS KB), which found no issues, but apparently reset the certificate database that the installer took issue with enough that the next time the opener ran, it completed successfully without having to scrub everything GTA off the PC and install the standalone.

 

We will try this on another victim to see if this is a valid workaround/cure, but so far, we are good.

    Another GTA update...another classic fail!   

    Based on the discussion, this error has plague GTA since at least 10/2019 - I stopped looking.   

     

    Hows that 'permanent' fix coming from the developers?

      - 1. Navigate to %AppData%\Local\GotoMeeting\<number>\

      - 2. Right-click on g2mlauncher.exe

      - 3. Properties - Signatures - Details

      - 4. Install this certificate to default

      - The client should work now
