In order to enable you to work offline using a network license, you now have the option of "license borrowing"
With a borrowed network license, you can use the software for a specified time period while disconnected from the network. Your license is automatically returned to the license server at the end of the day on the return date you set when you borrow the license. You can also return a license early. The maximum borrowing period is six months.
You can return the license sooner than planned by clicking to open the Product License Information, then clicking Return License.
