First run needs internet access. In MT5 Expert Advisors options, the License server URL must show HTTPS and match exactly to avoid activation failure.

FAQ
I see a WebRequest error. What should I check?
Re-open Tools > Options > Expert Advisors and confirm "Allow WebRequest for listed URL" is enabled and the URL is exactly "https://license.goldenedge.ai" with HTTPS.
My key says already used. What does it mean?
The key may already be bound to another MT5 account number. Use the original account or contact support with your purchase email and MT5 login for reassignment help.
Can I use the same key on demo and live?
Demo and live accounts usually have different account numbers, so they are treated as different activations unless your plan explicitly supports multi-account usage.
Where exactly do I paste my license key?
Paste it in the EA Inputs tab after attaching to chart, in the license key field. Do not add extra spaces before or after the key.
Setup complete? Keep MT5 running and monitor the Experts tab for normal heartbeat logs.
