Secure Licensing
Secure hybrid activation
Choose a one-computer or two-computer entitlement. Online activation verifies the signed entitlement and refreshes the local license lease. A limited grace period helps a valid installation continue through a temporary connection problem, and owner-approved offline recovery is available when needed.
Computer-bound seats
Each activation is tied to an authorized Windows computer. Deactivate the old computer before moving a seat.
Signed licensing
The application verifies signed license information. Owner private signing keys are never included in the app, website, installer, customer backup, or support package.
Clear recovery path
When online activation cannot be used, create an offline request and install the owner-signed license returned by support.
