I am an online student of PCDI ASHWORTH COLLEGE, Canada, and currently running a program on AutoCAD. I am due graduating this August, 2023. My computer is 2012 version of MacBook Pro and that is good for AutoCAD 2020 Software version.. Recently, the Application Software started to malfunction. I uninstalled the App and hoping to re-install it, I emptied the trash after that. I tried to re-install it again only to discover that it has been discontinued. Big issue for my program. Help me!
