"License not found" or activation errors
Bluebeam shows licence errors or says it cannot find a valid licence.
Critical — Read Before Proceeding
If the error message mentions 'Revu 21' or a 'subscription required', you or someone else may have triggered an upgrade. Contact IT/Admin immediately — do not attempt to fix it yourself.
