The thread you referred to did not answer my question.
Specifically, I created a document using Haettenschweiler in CS6.
I moved the file to CC.
"Haettenschweiler" shows up in my font list, but I get an error that the font is missing.
It is listed in the fonts available through my computer's Control Panel.
I noticed in the InDesign font list, there are some fonts with a black arrow in front. What does that mean?
Does Haetenschweiller show up in the ID font list?, if not, and it's installed, the answer is in the other thread, but may not have been at the time I linked. You have filtering turned on in the fonts list. Without a pictrue of the arrow I'm not sure, but I suspect it's the icon for Typekit fonts.

in my case I'm using WIN I can dispose of all the Fonts I copied into my fonts Directory. Here a screenshot of my German Indesign, where you can see this "Haettenschweiler":
What concerns these little black arrows, they are an indication of some more type variants (see screenshot):
