Canon EOS 7D

I have spent the last 2 days trying to get a live video feed on iSM 3.6 (if it actually opens - see other post!), but to no avail. It is a camera that iSM says it supports, but it doesn’t work. I have tried the ‘no application’ option in ‘image capture’, that doesn’t work. I’ve changed a lot of the settings on the camera. I need some help from others please!
