Re: GoTo Opener Error "Timestamp signature or certificate could not be verified or is malformed

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
