Installed CC fonts do not appear in non-Adobe software.

I am trying to create PDFs from old, old files (primarily QuarkXPress, though there are others). My company does not allow me to install fonts that I download from 3rd party sources (DaFonts, etc.) due to security concerns.

Many of the fonts I need, are owned by me personally, purchased from legit type foundries. However many are not. I have them via Creative Cloud, but they are not showing up in Quark or other non-Adobe design software.

Where are the .otf files so I can drop them into FontBook so I can actually use them to create the pdfs needed as opposed to re-creating massive files from 20+ years of work into InDesign.
