How to Activate using License Key

It's very easy to activate Vovsoft products using your license key. If you don't have one, you can purchase a license key right away.

Online Activation

The "TRIAL VERSION" window opens automatically. You can also access it from the menu:
Help > Edit License

You only need to enter your license key and click the "OK" button.

Forgot your license key?

Are you getting a "The server returned an invalid response" error despite having a valid license key?

• Please ensure you downloaded the software directly from our official website. Unauthorized or modified executables are known to trigger this exact error message.
• Please check your antivirus, firewall, and proxy settings to ensure they are not blocking the software.

Are you getting a "Activation Failed" error despite having a valid license key?

• Disable your VPN: While most VPNs work perfectly, certain strict routing configurations can block the activation. Try disabling or uninstalling your VPN client.
• Change your system locale: As a temporary troubleshooting step, open your Windows Settings and try changing your Windows system locale to "English (United States)" to rule out rare regional conflicts.
• Create a new Windows user: Sometimes, profile corruption or hidden permission restrictions can prevent activation. Testing the process on a freshly created Windows user account can help bypass these local system blocks.

If you can't activate using online activation, you can activate using Offline Activation.

Offline Activation

If you are behind a strict firewall or completely offline, you can activate the software manually.

1. Go to the self-service Client Area and log in.
2. Click on Offline Activation.
3. Enter your License Key and Computer Code (your computer code is displayed within the software).
4. Click the Get Activation Code button.
5. Copy and paste the generated Activation Code into the field in the software.
   (Note: Please disconnect your computer from the internet before activating. Otherwise, the software will try online activation.)

Activate without manually entering license key

To activate your Vovsoft software automatically, create a simple text file named key.txt and paste your license key inside it.

• If you are using a portable version:
  • Just place the key.txt file inside the same folder as the program's executable file.
• If you installed the software on your computer:
  • Copy the key.txt file into the same folder where the program is installed (usually inside the Program Files folder). Put it next to the program's executable file. This will activate the software for all users on the computer.
