Looks like the same problem: > [@Unity BuildPipeline.BuildPlayer & DllNotFoundException: fmodstudio](https://qa.fmod.com/t/unity-buildpipeline-buildplayer-dllnotfoundexception-fmodstudio/17122): > > We have an automated build process that uses Unity’s BuildPipeline.BuildPlayer and in this case it is told to make a StandaloneWindows64 target with BuildOptions.StrictMode. Later on in FMODUnity.Settings.BuildProcessor.OnPostProcessBuild the DLL that gets chosen is determined based on whether EditorUserBuildSettings.activeScriptCompilationDefines.Contains("DEVELOPMENT\_BUILD"). These two things don’t seem to match up, or at least Unity does not seem to update EditorUserbuildSettings when using… Successfully fixed by by adding `|| report.summary.options.HasFlag(BuildOptions.Development)` to check in FMODUnity.Settings.BuildProcessor.OnPreprocessBuild: ```auto if (EditorUserBuildSettings.activeScriptCompilationDefines.Contains("DEVELOPMENT_BUILD") || report.summary.options.HasFlag(BuildOptions.Development)) ``` May be will try to upgrade to 2.01.10 later --- _[View the full topic](https://qa.fmod.com/t/we-got-java-lang-unsatisfiedlinkerror-couldnt-find-libfmodl-so-when-running-development-build/17445)._
