I can't activate AdGuard with my license key

There can be several possible reasons:

You have entered your license key with a typo. Please doublecheck it.
You have reached the maximum amount of active devices for your license key. Go to your Personal account and reset license for any of the active devices to be able to use it on a new one.
Your license key has expired. You can check it in your Personal account.
You have a license key of the old type that differentiates between mobile and desktop AdGuard applications. You're trying to activate AdGuard on a device of the type that your license key doesn't allow you to. To get more information, check your Personal account or contact our support team at support@adguard.com.
