Frequently Asked Questions

Who can use this tool?

Only customers who purchased their license keys from keys4us.com with the same email they enter here.

What if I see "No purchases found for this email"?

  • Check the spelling of your email.
  • Ensure your order is completed and not refunded.
  • Confirm you purchased from keys4us.com, not another site.
  • If it still looks wrong, contact support with your order number and a screenshot.

Does reusing the same Installation ID use another activation?

No. The same Installation ID for the same email returns the existing CID without using any new activation credits.

Why do I have limited activations?

Your available activations are based on valid completed orders at Keys4Us. Each new, unique Installation ID (new device or major hardware change) may use one activation from your balance.

What if nothing works?

Double-check your email and Installation ID. If you still cannot activate, take a screenshot of the activation screen and contact Keys4Us support with your order details.
