Does anyone know if the original Realflight is compatible with Windows ME or just with Windows 95/98?

I have seen listing some places that only list 95/98 & some that also say ME, so I just want to be sure.

Funds are kind of tight right now & I was thinking of just getting a used original instead of G2 as I've seen them selling for half the price. If it doesn't work with ME ,then I guess I'll have to bite the bullet & get a G2.

Thanks,

John
