Fmod DLL error in Steam builds

Getting this missing FMOD dll error in our steam builds. Specifically when we build in non-development mode in Unity.

Any ideas why?

Does the FMOD dll need to be set to include for non-dev builds?

Unity version: 2021.2.15f1
Fmod version: 2.02.04

Is the dll present in your built game’s “{ProjectName}_Data\Plugins\x86_64” directory? If it is, does it have a reasonable size (~3000kb)? If it isn’t present, can you please check the import settings for fmodstudio.dll inside Unity, and make sure it is set to be included on Standalone Windows x64? e.g

thanks, will check this!
