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? Then you should try activating offline.
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.
