Is it possible to get this back?

I bought the HP Pavilion DV9700.
I like using the web cam that it comes with a lot. It came with Cyberlink Youcam already installed but I downloaded a free trial version. ( IDK why)

Now I lost the Cyberlink Youcam Program that already came with my laptop and all I'm left with is the trial version ( that's about to end soon).
Is there anyway I can get the program back without buying the program?
