Your program file may or may not be a single file, in your case you have installed it and it works, so let us go on to the additional downloads. Those are content packs that may include things like Titles, PIP images/animations, menus, music, and FX.
I personally would install them just so I don't miss anything, particularly FX packs. I capture tape a lot and I like the FX because both Boris and New Blue have "restoration" filters, much needed in old tape captures.
Whatever you decide, be sure to
not delete your downloads, so many people come here looking to replace their lost downloads.
