ITC Officina Sans and Officina Sans Adobe

Good Morning:

My department is having an issue regarding the font ITC Officina Sans and Officina Sans Adobe. 

Our computers have 2 versions of Officina Sans - 1 says ITC the other says Adobe.   One of my coworkers used the Adobe Officina and I use the ITC so when I opened an Illustrator file of hers my computer doesn't recognize her font. I tried downloading both separate fonts but it keeps saying that I am downloading a duplicate font and doesn't merge the 2 or update the fonts.

How do I solve this? I need to have my Adobe programs recognize that both version of Officina are the same across all of our computers.

THank you
