On my master control pc I have Multiplicty pro installed. But on each additional pc only regular Multiplicity installed
To be clear, there is not a 'Pro and regular' version of the installer. The key itself determines what it is, not the installer.
It only allows for one pc to actually have the pro version installed.
Following what I wrote there, 'only 1 Primary is allowed to be activated per license'. What is odd is that the prompt to activate should still happen when one tries to promote a Secondary to a Primary, allowing you to demote the currently activated Primary in the process... To boot, this all needs to happen regardless if the user has finished creating an account.
If something is happening to usurp that, we would need to know. We are testing it.
