Isolator++ license not working [closed]

I downloaded Isolator++ and activated the license using the activation link. When I try to run unit tests it gives Assert failed. License check failed

Please run Isolator++ Configuration tool.

I ran the tool and entered the activation code from the email there and it seemed to accept it. However I still get license check failure when trying to run the unit test.
I am using MSTest in Visual Studio 2022, but building using 2013 tools.

Thanks,

Mark
