I can’t build for windows any more. I get strange erros like: Assets/Plugins/FMOD/BankRefAttribute.cs(5,37): error CS0246: The type or namespace name `PropertyAttribute’ could not be found. Are you missing an assembly reference? Assets/Plugins/FMOD/FMOD\_Listener.cs(5,30): error CS0246: The type or namespace name `MonoBehaviour’ could not be found. Are you missing an assembly reference? Assets/Plugins/FMOD/RuntimeManager.cs(370,91): error CS0246: The type or namespace name `Transform’ could not be found. Are you missing an assembly reference? It’s like fmod cant find unity anymore? Using unity 5.6.3f1 and fmod 1.10.00 Building any other platform works. Tried re-installing unity, rebooting, re-importing plugin. rebuild fmod project nothing works, tried it on a new blank project as well. ---

Something definitely isn’t right, before re-importing the plugin can you try deleting the Assets/Plugins/FMOD folder. If that doesn’t work I would suggest downloading the plugin again. ---

Removing Assets/Plugins/FMOD and redownloading and re-importing did not fix the problem. any reference to unityEngine seams to fail Assets/Plugins/FMOD/StudioParameterTrigger.cs(64,30): error CS0246: The type or namespace name `Collider2D’ could not be found. Are you missing an assembly reference? ---

You said “It’s like fmod cant find unity anymore?”, what happened in the time since you could last build for windows? ---

stopped working after the first build of a different platform. built win worked. switched to mac, built mac, built worked. switched back to windows, build cant find unityEngine. switching around, reinstalling unity, moving project, all fails now. ---

The only reason I can see that you would be getting these errors is if the “using UnityEngine;” was missing from the files. ---

yeah its there on all files. So it’s a strange local problem. Building on any other computer or platform works, even unity cloud works.
