Activate a License

Activate the DoorFall license key for the installation domain.

During installation

Enter the license key exactly as supplied by DoorFall when the installer requests it.

The activation is associated with the installation domain.

If activation fails

Check:

  1. The license key was copied completely.
  2. The domain has internet/DNS access.
  3. The license key is not still activated on another domain.
  4. Temporary network/security rules are not blocking the request.

If the problem remains, open a DoorFall support ticket and include the license key in the required support field.

During installation

Enter the DoorFall license key supplied with the product purchase when the installer requests it. A DoorFall Start Page Script key normally begins with DFSP-.

Example format:

DFSP-XXXX-XXXX-XXXX-XXXX

What activation does

Activation associates the license with the current installation domain. If the license is already active on another domain, deactivate the previous domain before activating the new installation.

If activation fails

Check:

  1. The complete license key was copied without extra spaces.
  2. The server has normal internet and DNS access.
  3. The license is not still active on another domain.
  4. A firewall or hosting security rule is not blocking outgoing HTTPS requests.
  5. The DoorFall licensing service is not temporarily unreachable.

A temporary licensing-service outage should not disable an installation that has already been successfully activated.

Getting help

When opening a support ticket, select the relevant DoorFall product/license from your customer account where available. Include the exact activation error and the domain you are trying to activate.

WARNINGNever publish your full license key in a public forum or screenshot.
