Activation and serial number errors
Every activation message – already activated elsewhere, moved too often, expired, wrong product, wrong computer – and what to do.
| Message | What to do |
|---|---|
| This serial number is already activated on another computer (…) | On the old computer: License → Deactivate on this computer. Old computer gone? Open a support ticket with the serial and we release it. See Move a license. |
| This serial number has been moved to another computer 5 times | The transfer limit is reached. Contact support. |
| This serial number expired on … | Renew from your account page. See Renew your license. |

| Serial number is incomplete / not valid / Invalid character | Copy the whole serial from the e-mail or your account page – it is long; don't retype it. |
