Why won't VOCALOID2 open?

[whiteglove]

Hey, so I had to re-install my physical copies of VOCALOID2 and SF-A2 Miki. Which I thought was successful, but I get an error code upon trying to open it, telling me 「合成エンジンを開けません！」, or "Synthesis engine cannot open!"
What do I do?
I did everything on the official Japanese CFM page(link here)
so im like really confused lol any and all help appreciated

I'm having the same problem as well! Were you able to fix it?

Do you have any other Vocaloid2 vocals installed? Vocaloid2 is funky and if you go with the default installation settings when installing voicebanks, then they'll need to be installed in release order. I had this issue when installing my Crypton V2s; I had installed them in the wrong order which was causing that error.
You may want to try installing the English updater as well.

Sorry for the late reply! I did fix it by changing my system locale to Japanese! At least I think. It's been years.
Anyways, my new problem is here!
