Hi, Unfortunately, I was not able to reproduce the issue. Could I get a screenshot of your `Platforms` folder in your Unity project: ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/b/b93ac087c6b4e7ce72819f3057dd237319b3c146.png) And you `About Integration` windows: ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/4/4e08bbc438855e62c168c9dfa2cd2769fb2b3c64.png) ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/a/a77bc3c4babf7c8c5e6e7a87ff74c11575d0301a.png) ---

Thank you very much for your answer I tried to create a new 2D project for Unity2022.3.16, but without adding FMOD files, I was able to print NS files normally. After adding FMOD, when building, I received an error message indicating this version This is the Asset file for my new project [Assets\_Fmod.zip - Google Drive](https://drive.google.com/file/d/1XL-C9SuCxInrjHtAdVcipgmUE8nil7Ap/view?usp=drive_link) ![fmod_01](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/b/b0198a8dcbffc36e95fd9c63e25732ac9998867a.jpeg) ![fmod_02](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/7/7d5a75468043de85f428607e2f7cc150da56c396.jpeg) ![fmod_03](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/3/31c655f1f64878353d315e036e43c4e552d341d4.jpeg) ![fmod_04](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/5/565867336aaa5ec5d01d973e3d3fa8bc855b936b.jpeg) By the way, I also tried the fmod switch version 16.2.6, which still has this issue Can you give me a rough idea of the direction of this issue? thank you very much indeed ---

Hi, Thank you for the screenshots. Everything looks in order. Could you look through these docs: [Unity Integration | Trouble Shooting Assembly Reference Error](https://fmod.com/docs/2.02/unity/troubleshooting.html#assembly-reference-error) and let me know if it solves the issue? ---

Thank you for your reply. I have resolved the issue because of my Unity 2022.3.16f1c1 and NS requires a version of 2022.3.16f1 One c1 is missing 😅 If any friends encounter the same problem, I hope they can see that they don’t take the wrong path ---

Hi I’m having this issue with Nintendo SDK 20.5.28 and Unity 6000.3.7f1 using FMOD 20.2.28 The issue only happens with Switch 2 as a target, any idea of what might be wrong? I tried to follow this an other ticket but they did not lead me to the solution. ```auto Error CS0117: 'VERSION' does not contain a definition for 'dll' Error CS0117: 'STUDIO_VERSION' does not contain a definition for 'dll' ``` ---

Hi, 2.02.28 does not support Switch 2. It is supported post 2.02.29, would it be possible to test updating the integration and see if the issue persists? ---

Yes I can try tu upgrade FMOD 20.2.29 but then I need that version to match Nintendo SDK 20.5.28. I already did a request in Switch 2 channel. ---

Any luck with the updated SDK integration? ---

@Connor_FMOD I got the matching library but there is an issue [https://qa.fmod.com/t/request-for-fmod-2-02-29-for-unity-and-sdk-20-5-28/24065/2](https://qa.fmod.com/t/request-for-fmod-2-02-29-for-unity-and-sdk-20-5-28/24065/2) Cheers, Leon
