Hi Brendan,
There is a way to do this. First, the admin has to install Isolator++ on their user.
Next, in your local user, you should be able to access the TypemockConfiguration.exe file in the installation directory, typically under: C:\Program Files (x86)\Typemock\Isolator++.
Open the configuration file and go to the license tab. Insert the registered email and license key and press Set License. Try running tests now to see if this works.
Hope this helps.
Best,
