Cannot build to Xbox One, says 'XboxOne' does not exist in namespace

Hello. I am currently porting a Unity project to Xbox One. As part of my build process, I receive the following error:

Assets/Plugins/FMOD/src/Runtime/RuntimeManager.cs(1047,18): error CS0234: The type or namespace name XboxOne' does not exist in the namespace FMOD’. Are you missing an assembly reference?

I am using a project prepared for me by the original developers (who have access to FMOD Studio) and thus do not have a way to edit the project. The project works fine when building for Windows.

Is there something I need to do to the project, some DLL I’m missing or some setting I need to change to get this to work?

Thank you very much.

It sounds like you are missing the FMOD for Unity Xbox One unitypackage which you can on the downloads page, if you do not have access to it console access can be enabled by verifying that you are a certified developer for a given platform. You must also register a project which is linked to that platform. Both of these steps can be managed from your FMOD profile.
