You can get your Activation Code instantly by using our Offline Activation Form:
- Go to self-service Client Area.
- After logging in, click Offline Activation.
- Enter your license key and computer code (your computer code is displayed in Vovsoft software).
- Click Get Activation Code button.
Make sure your computer is disconnected from the internet before trying offline activation.

Activate without manually entering license key
⚠️This is an online activation method.
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 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 file. This will activate the software for all users on the computer.
