Available options for controlling the expiry date of a license

Applies to:

QLM Pro and QLM Enterprise.

QLM: 8.0 or higher.


When specifying the expiry date criteria of a license, you can configure two settings:

  • Expires <x> days after install

  • Expires on <date>

If you configure both settings, the license will expire when either setting's criterion is met.

If you configure a duration-based expiry and select to expire the license x days after installation, the actual expiry date is controlled by two server properties:

useDurationToSetExpiryDate

When creating an Activation Key with an expiry duration, the QLM License Server converts the specified duration to a specific expiry date based on the current date. The SubscriptionExpiryDate field will be set to this expiry date.

useDurationToSetExpiryDateWhenActivating

When activating a duration based license, the QLM License Server can convert the specified duration to a specific expiry date based on the time of activation. The SubscriptionExpiryDate field will be set to this expiry date.

If both server properties are unchecked, no specific expiry date will be set. The license expiry date will be based on the first time a license is validated on a user's machine. This setting is not recommended as it is less secure.
