MIdiJack DLL not found

I'm working on a project that uses the midijack plugin and works when testing within unity, but when I publish it as a standalone or windows app it comes up with the error "DllNotFoundException: Not able to load DLL "MidiJackPlugin" the specified plugin cannot be found."

Right now the dll is in the project folder under Assets/MidiJack/Plugins/x86/MidiJackPlugin.dll as it was when the package was imported.

Any ideas?

Thanks!
