When you re-install the VOCALOID2 in the same computer, you don't need to activate it again, as activation information is already stored in the computer.

However, when you re-installed the OS or changed the device used for the previous activation, then you need to activate VOCALOID2 again.

When you get this message before/during activation, please check the followings;

• Make sure the VoiceDB which need to be activated is installed in your computer.
• Make sure you're logging in as administrator. To install/activate VOCALOID2 you must have Administrator rights.
• It is possible that some resident software, such as anti-virus software (such as Norton) and/or security software is affecting VOCALOID2 activation. Leave only the minimum process to run Windows and turn off all the other resident software, then try activation again.
