Hi there, I am trying to have my VW license on my laptop and PC. However, everytime I try to activate it on my laptop, it says that "VectorWorks cannot be activated because the license has been activate on the maximum number of machines allowed". I even tried uninstalling it on my PC and reinstalling it on my laptop, but still no luck. Is there any way I can see what computers have the license activated and manually remove them? Any help would be appreciated. Thank you, Ous
