The Final Fall Creators Update Build is 16299.15 add released CU (KB4043961) and you get 16299.19. There is no 16299.19 ISO.
First, read the OP, you can get 16299.15 enterprise on the techbench dump (top link of my sig) or as full clientbusiness ESD.

I converted the Enterprise ESD and installed it yday. No problems so far. The build seems more stable than 1703.
I upgraded to 1709 on my tablet, everything seems to works but I have lost the automatic rotation of the screen and I don't see any options to enable it, do you know how to fix that ?
