When you are away from school you may have trouble launching AutoCAD because it cannot reach our license server. You can work around this by borrowing a license while on-campus. This will give you a period of time where your software doesn't need to check-in in order to launch. If you have trouble borrowing a license from home, check your VPN connection.
Launch AutoCAD.
In the command bar at the bottom, type the command, BORROWLICENSE and hit enter.
In the Borrow a License window, choose a date up to 90 days in the future. This is when your borrowed license will expire.
Click Borrow License.
A window will appear confirming you've borrowed the license. You can close the licensing and about windows, then continue using AutoCAD.
