FMOD and Unity Integration Errors

I’m having some trouble integrating FMOD and Unity together. When I import the FMOD package I get a few errors(shown below). I’m curious has anyone experienced these before. any help would be appreciated. I’m using FMOD 2.0 and its happening on Unity versions 2017.2 and 2017.3. Is it as simple as that these versions of Unity are not compatible with the FMOD I’m using?
