Connecting Ableton

If I put TDAbleton in the folder and run the touch designer to update it, won’t it connect?
No matter how hard I try, I can’t connect.

Are you trying to install to a custom location? Did you try running as admin? There are instructions in the wiki for installing the folder by hand here TDAbleton - Derivative

I don’t know how to update the version…
