Launch Switch from Ue4

Unreal Engine

Hi!
We are trying to launch our project to the Nintendo Switch Edev from Unreal. The launch ends with this message:

LogPlayLevel:   Building 4 actions with 8 processes...

Fmod works for windows. We can’t see Fmod as an option in the help menu in Unreal.
We have installed the fmod Switch plugin in the root of the project as the documentation showed.

We are using UE 4.26.2.
And “fmodstudio20205ue4.26switch_sdk10.4.0” for the switch plugin.

Any ideas on what’s wrong?

Thanks!

Any news or updates on this?

Have you recently updated from an older version of FMOD or is this a fresh install?
FMODPlatformLoadDll was removed in 2.02.05, but I think it would be possible to hit this error if you had a base installation of 2.02.04 and a Switch installation of 2.02.05.
In any case, I would suggest removing “Plugins/FMODStudio” from your project, redownloading the 2.02.05 plugin for Windows UE4.26, and adding that back into your project.
Please let me know if you are still getting the error and I’ll take a closer look.
