The license will be installed and an Activation Success screen will appear.
Click OK.
If the free license is running, then disconnect from PCPro and then go into
TelePro. Change Program 90-55-01 from 1 to 0 and exit from programming.
If the free license was not running and then a license is installed, you should
set Program 90-55-01 to 1 and then change it to back to 0. Once you have
toggled the free license then connect to PCPro you will see that some items
that are not licensed have a status of being Off.
