I havent got access to Ableton atm But from memory, you go to the plugins button which is on the top left, beneath the triangle button and the Instruments/effects button and above the 1 2 3 file browser buttons. You go to plugins and it should have a button you press to apply settings. Go to it, designate a folder for all your plugins. Now reinstall the auto-tune and when it asks where to install the 'vst' install it in the folder you previously designated.. yeah?? otherwise, install the whole program in that folder. IF it doesnt require installation, then just find a file that ends with .dll ie antares.dll and put it in the plugin folder you designated. Once you done this, scan for plugins in the settings box in ableton, or just restart ableton. OK... so now it pops up in the plugin panel... you can double click on it and it will either: apply itself to an audio track/midi track OR it will open up its own, or you can just drag it accross
