Activation Guide
Go to Settings → Update & Security → Activation (or System → Activation).
Click Change Product Key and enter your 25-digit key.
If the key does not activate immediately, use the phone activation method:
Step-by-step to get your Installation ID (IID):
On the activation screen, click "Activate by phone".
A window will appear with an Installation ID (IID) — a long number (9 blocks of 6–7 digits).
No actual phone call is required. Take a screenshot or write down this IID.
Once you have the IID, choose one of the options below:
Option 1 – Fast via GetCID (recommended)
Go to
https://getcid.online/ru , enter your IID or upload a screenshot — the service will automatically generate the Confirmation ID (CID) for free and instantly.
Option 2 – Send IID to me
Send me the screenshot of the IID and I will generate the CID and send it back to you.
Where to enter the CID:
Return to the phone activation window on your PC, select "Enter Confirmation ID", type in the CID, and activation will complete successfully.
