- Verify that all interactor keys are activated within Manage Product Keys. For more information, see Add Capacity to Tableau Server.

When attempting to add a new user or assign a site role to a user on Tableau Server, the Tableau Server environment has reached or exceeded the total number of available interactor seats.
It makes since in my head why you get the errors. So JP is taking the only seat available. You can't assign yourself the admin role because that one seat is taken already. You can't unlicense JP to add yourself because you won't have an admin user. So you're kind of stuck :(.
In my head the easiest solution is to temporarily assign one more license, add a second admin, unlicense JP, and then remove the temp license. Either that or allow Tableau support access and have them unlicense JP and add you as the admin. Your best bet is to reach out to support:
Best of luck,
