Working with Time-limited Licenses
Certain licenses have expiration dates.
To check the expiration date of your license
1. Open the license key file in a text editor.
2. Locate the element ExpirationDate.
If this element contains the value Unlimited, then there is no expiration date, that is, the use of the license is unlimited. If this element contains a date, this date is the last date for which the license is valid.
