Thought I had posted this so if duplicated sorry about that..
I have a 7D and watched this which explained the setup but do I have to use Live View due to the clunking in the camera and delay taking photo ? https://www.youtube.com/watch?v=bg2U2vxBir8
I downloaded the one for windows but it isn't Utility 3 and the drop down for Av etc are right click horizontal.
If there a one of these that just shows what the viewfinder sees ? Save my knees hopefully, maybe the mini hdmi can be used to show what the viewfinder sees ? That would do for me as just occasional use
