add external Python DLL to installer project

Hello all,

I've got an installer project, but can't seem to add a python DLL. There are vi's that use the DLL but for some reason the project is not adding the python DLL. I've tried doing the Project > Add to Project, but that doesn't let you add random files, just Labview files. Not sure why it's so restrictive. 

Any help would be appreciated.

Thanks,
