License & Activation

Your license

We email you a license key when you buy, and it is always available from your account page. One license activates the E3X on up to 2 machines at once (a desk PC and a sim PC, say). Activation binds the key to a fingerprint of this machine (an ID from the board on Windows, usually from the OS install on Linux). The E3X keeps a signed activation record and checks it offline at every start. It refreshes the record with the license server about once a week when online.

Activating

Paste your license key into the installer when it asks. That is the whole flow. Did you install without a key (demo mode), or are you activating a second machine later? Run this from the install’s core folder (./e3x-core on Linux):

e3x-core license activate <KEY>

Activation contacts our license server once. After that, the machine stays activated offline. e3x-core license status shows this machine’s activation any time.

On Windows, the user accounts on one PC normally share a single activation and slot (one place on the license). A per-user Linux install normally cannot write the shared copy, so a second account on the same PC takes its own slot.

Moving to a new computer

Deactivate the old machine, then activate the new one. To deactivate, run e3x-core license deactivate on that machine, or use your account page if it is dead or inaccessible. Occasional moves are normal and expected. Rapid repeated cycling is rate-limited. If you hit the limit legitimately, support will sort you out.
