There are some people who've had trouble with 8 and later Windows versions, though V1 is by far worst for its instabilities.

There is also no reason to go after V2, since V3 was superior in just about every way, plus it registered V2 voicebanks so and they generally sounded better on the engine.

V4 is basically the Windows 10 update of Vocaloid, since it came in with Windows 10s release (a lot of software had Windows 10 updates that year). So everything before V4 was not made for Windows 10, though V3 seems to be the only one of the effected versions that has no issues with Windows 10. I can't remember what it was, but V2 had a problem with Windows 10 for some. As I said though, V1 is by far in a worst state....
