Offline licensing

An offline computer can use a signed license without contacting the website. Obtaining or renewing that file requires access to the website from another computer.

First activation

  1. On Redline's activation or account/license screen, find Activate offline. Choose Copy request or Save license request to file....
  2. Transfer the copied request or exported .lic request file to an internet-connected computer. The request is base64-encoded JSON; legacy JSON requests are also accepted.
  3. Open your individual subscription or company account, then paste the request or upload the file under Offline activation & renewal.
  4. Choose Export license key and transfer redline.license back.
  5. Paste the file's contents into License key and choose Activate, or choose Load license from file....

The request identifies an installation, not a drawing. It contains no project content.

Renewing

Paid files expire 15 days after the Polar key expiry. Yearly paid files can remain usable offline for the full year plus grace. Renewal uses Polar's current expiry and does not reset a rolling clock. The desktop renews daily online and warns during the final paid grace period. Offline renewal uses the same upload process. Trials last 30 days with no extra offline grace: trial files expire at the earlier trial/key end, and billing can start after day 30. There is no account-age trial.

The displayed Valid until time is the final authoring expiry, already including paid grace. Grace begins at the provider key expiry, not when the computer loses its internet connection. Reconnecting or downloading the same license does not restart grace; access extends only when the provider supplies a later expiry.

For offline renewal, reuse the same installation request on the account website and import the newly downloaded license. The licensed computer can remain offline throughout. Signing out removes automatic online renewal credentials but does not invalidate an already issued file.

Replacing a machine

Manage device activations in Polar's portal. Each key allows two activations. Deactivating a device releases its activation slot; it cannot erase a valid file on an offline computer or permanently block that installation. If the old computer remains signed in, automatic renewal may activate it again and reclaim the slot. Sign out on the old computer before releasing its slot. Export a request from the replacement machine to activate it. No first-party activation database is maintained.

After expiry

A compatible desktop release preserves viewing, exporting, and recovery saving while restricting authoring until a valid license is imported.
