I have purchase Draftsight Premium on 9th September 2020 and successfully installed and have been using is so far. But due to some issues in my system (Laptop) I have formatted my system and reinstalled windows 10 again. Thereafter when I tried to installed Draftsight again message "Activation transaction failed: Activation count exceeded. Deactivate a license from another computer and retry. Visit My.SolidWorks for more information. (3/0)"
