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](https://www.fmod.com/download) 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](https://www.fmod.com/profile#permissions).
