Wrong XInput linked on UE4.24+ Windows. Incompatible with Windows 7.

+2 votes
The Wwise UE4 plugin contains this block of code:

#if UE_4_24_OR_LATER
        PublicSystemLibraries.AddRange(AkUEPlatformInstance.GetPublicSystemLibraries());
#else
        PublicLibraryPaths.AddRange(AkUEPlatformInstance.GetPublicLibraryPaths());
        PublicAdditionalLibraries.AddRange(AkUEPlatformInstance.GetPublicSystemLibraries());
#endif

This causes the project to link to XInput1_4.dll when compiling on Windows 10, which is a pain to support on Windows 7. As such Unreal only uses XInput1_3.dll.

We have reenabled Windows 7 support in our title by removing XInput from AkAudio_Windows.Build.cs:
    public override List<string> GetPublicSystemLibraries()
    {
        return new List<string>
        {
            "dsound.lib",
            "dxguid.lib",
            "Msacm32.lib",
            "dinput8.lib"
        };
    }
