The Expiration Tab is the tab on the License Project Properties dialog where you define any expiration data for the license. To get to it, open a license project file in the SoftwareShield License Manager and click on "Expiration".

The tab looks like this:

On this tab you can set any or all of the three mechanisms that can cause a license to expire. The execution limit and expire period can both be set to any number between 0 and 9999.

The Last Used fields indicate the last date and time the license was used and is checked when the ClientProtector loads a license for the first time.  We recommend that you reset this date and time to the current date and time every time you recompile your license using the "Reset To Now" button.
