It's very easy to activate Vovsoft products using your license key. If you don't have, you can purchase a license key right away.
You only need to enter your license key and click the OK button.
Do you have a valid license key but still get "Activation Failed!" error?
Please note that offline activation is only available for paid license keys.
If your computer is not connected to the internet or is behind a firewall which blocks online activation, you can activate Vovsoft products using the offline activation method.
You can get your Activation Code instantly by using our Offline Activation Form:
Make sure your computer is disconnected from the internet before trying offline activation.
