Adobe Anywhere is an enterprise solution with high overhead.
CS Review was pulled after a couple of release cycles. I'm not privy to the why's and wherefore's.
Two suggestions:
- Have your client install the trial version of Premiere or, probably better still for this purpose, Prelude. Then they can import the video (your encoded output, not the project...) and add markers with their notes--with duration if desired to mark a span. The markers are saved to the clip, so you'll see them when you import the clip into PPRO. Then you can drop that clip on the top track of your working project and walk through the notes.
- Go old-school: Burn timecode into the review video, and have the clients reference the timecode in their notes.
