Seems that Adobe is dedicating this one!
I took a screen shot of the two programs opened at the same time, in the same page #7 of the first part of the download. At Foxit Reader on the left, it's blank. The one on the right is Adobe. Versions are noted. Using another pdf viewer, PDF Architect, I can see all the content. However, it's slow to load each page compared with other documents or manuals.
