Do you mean in Ableton Live control surface list?
I talk about list in Ableton preferences to configure materials (Midi Sync). First list to ckeck LK. I have not LK. Thanks
I have the same problem no "LK" on available Ableton Live control surface list..
You need open LKBRIDGE and under Ableton Live section, you need to click the plus button and select Ableton Live app. You can also drag Ableton Live onto the windows to install. Dragging shortcuts under windows don't work. Have you followed these steps? If so, you might need to install it manually as something related with permissions is allowing you to write. But if you haven't followed this steps, please try, is much easier. Check out this link too: https://www.imaginando.pt/products/lk/help/setup
