Hiya, I've been getting the same errors with the bridge plugins as basically everybody else (Voice engine [VOCALOID6] failed to init: Could not load type 'Yamaha.VOCALOID.VSM.Renderer.ObserverCompleteEventHandler' from assembly 'VOCALOID6Plugin, Version=6.7.0.1, Culture=neutral, PublicKeyToken=null'.)
I managed to fix the Vocaloid5 not installed error by simply installing the v5 editor itself, but now the ability to set a voice no longer functions leaving my voicebanks inaccessible. EDIT: Vocaloid5 banks work again after a fresh reinstall of all voicebanks.
In my troubleshooting I tried to see if TuneLab still functioned on my old laptop which has been offline since 2025 due to the wifi chip failing, and it still functioned as intended. I attempted to move this old TuneLab version to my current laptop, but was hit with all the same errors despite what I thought was a completely fresh reinstall after deleting all files.
Is something in the way of rolling back to previous versions? Or am I just very unlucky?
Also - any general help with the V6 bridge plugin errors appreciated. Fixing that would mean I could avoid doing this tomfoolery to begin with.
