If someone else like me finds this, don’t forget to look in the exact file path tlongabaugh mentions. There will be a seperate Steinburg folder in “Program Files” not nested under “Common Files.” The .dll file won’t be there. 

 

I recently switched from Pro Tools — which never had as problem finding all my plugins on its own, to Ableton. It took a little doing to get my VST2 Plugins found. I ended up setting up: C:Program FilesCommon FilesSteinberg as my “VST2 Plug-in Custom Folder” and moved all my .dll files over there. They showed up in Ableton Live and worked after that. There might be a less convoluted way to solve this problem, but this worked for me.
