For anyone wondering how to run version 1.4 (clean install on new PC) - you have to navigate to where you installed Reality Capture from EG Launcher (i.e. “C:\Program Files\Epic Games\RealityCapture”) and run “RealityCapture-1.4.0.msi”. This will install it default in: “C:\Program Files\Capturing Reality\RealityCapture” and from there you can run it with “RealityCapture.exe”. Other solutions did not worked for me.
