Hey i just bought z3ta + i installed the b4 bit version but its not showing up on my vst plugins in live
Hi, I just got Z3ts+ as well, hard to resist for $20 
Ableton is only available as a 32bit program, so even if you have a 64bit OS it will only run 32bit mode so you need to use all 32bit VSTi. Lets hope that V9 brings propper 64bit support (and dual screen)!
I hope that helps.
