"Since I don't have admin rights to my computer I'm not sure where they are installed."
Hi gailm74253389,
you can look that up even without having admin rights.
At least you can do this with the machine where no fonts are missing.
Menu Edit > Find Fonts…
Here you see all font styles that are used in a particular document.
Select one and go to "More Info…" and you can trace more Information about a used font.
Under item "Path:" you should see where the font style is installed.
A workaround:
Create a folder named exactly Document fonts in the folder where your InDesign document file is positioned.
Put all necessary font files for that document to that Document fonts folder. Restart InDesign and open the document again. Now all missing fonts should be available.
