Other than stumbling myself on different installation problems over the years, this is not a problem, just a possible suggestion.
MY all time favorite instructional video is where, You start the video, it shows you the first step with exactly what you’re supposed to be seeing and doing. AND THEN THE IMPORTANT PART. A VOICE SAYS: STOP THE VIDEO AND DO THIS STEP. ONCE YOU’VE COMPLETED THIS STEP RESTART THE VIDEO FOR THE NEXT STEP.
It’s really boring and simplistic but it it’s pretty effective IMO.
Also if you have to query the user about a glitch, you can ask them exactly what step they were on when something went wrong and you’ll know exactly where they were.
