We are encountering Tableau license issues across the library public computers. We have a fix but not enough time to implement before the end of finals. For students who encounter the issue, there are two paths – 1) if 201 is not-in-use, swipe them in for the duration of their assignment; 2) if you open & close Tableau a few times, it may eventually ignore the pop-up error the student receives. The issue will be fixed for the spring semester.
