First, make sure you've installed the original plug-ins!
Then you can put these devices into your User Library, basically anywhere.
Default location of the User Library:
When you install Live for the first time, the User Library is created at this location:
Windows: \Users\[username]\Documents\Ableton\User Library
Mac: Macintosh HD/Users/[username]/Music/Ableton/User Library
Please note that Live has to analyze your User Library after you put your devices in there. It could take a while.
For the time being, you can just drag and drop these devices onto your track from your User Library
