Support Information
About Product Serial Codes
Please keep the serial code in a safe place, as it will be required when reinstalling the software. Serial codes cannot be reissued under any circumstances.
If Activation Fails
If activation fails, check your Internet connection, LAN card installation status, and serial code. Enter the serial code in upper case one-byte alphanumeric characters. Also, make sure you have not entered the serial code of another VOCALOID product. If a network error occurs even though you are connected to the Internet, it may be due to resident software. In addition to Internet security and anti-virus software, utility software for the mouse and trackball may also prevent proper activation. Please temporarily stop/disable all resident software before activation.
