Unable to deactivate VOCALOID product due to PC failure.

VOCALOID software is designed to allow up to three activations per serial number for valid reasons, such as replacing a PC due to a malfunction.

Therefore, please try activating the software on your new computer first.

If you receive an error message stating that the activation limit has been exceeded, we can reset the activation count for you. Please contact our Technical Support and provide your activation code (serial number) and the library name (e.g., "HATSUNE MIKU V4 ENGLISH").
