Q. I have both "Megurine Luka V4X" and "VOCALOID4 Editor for Cubase" installed on my computer. In this environment, the VOCALOID4 Inst window displays a message in red, saying "VOCALOID4 module initialization failed(Error Code:83100411) No voice libraries are not installed." Also, the "Open VOCALOID4 Editor" menu command does not appear in the "MIDI" menu.
Update your VOCALOID4 Editor for Cubase to the latest version.
The updater for the latest version is available at: Download
