It is possible to lock a license or check if a subscription or maintenance contract is still valid. If the license is locked before the Serial Number key was already used, the product activation will fail. If the Serial Number key is locked after the activation was already done, then a regular online check is necessary to lock / revoke the license.

 

You can lock each module / feature separately.

 

•On the Activation Server Home TAB, search for the Key / ID (or TAB Manage Activations, Key List or Transactions)

•Click on the Serial Number and check the field: IsLocked
