Adobe CC executable files locations?

I am running Adobe CC subscription on a PC (Windows 10 Pro). I use a Kensington track ball, and I want to assign some properties to the trackball that are specific to Lightroom and Photoshop. In order to do that, I need to be able to locate the executable files for both Lightroom and Photoshop so that I can assign them within the software for my trackball which isn't automatically detecting either program when they are running, so I have to do it manually. Could someone please tell me where the executable files reside for the various Adobe CC programs?

Any help is appreciated. Thank you in advance.
