Does the movie have something to do with aliens? Is the Crystal Skull an alien skull?

How do I install Crystal Skull in my laptop with vista? This is one of Nancy Drew games that should run with vista. I only have the option “Install/run”. I tried installing it to another laptop I have that runs windows xp and it went so easy. I just inserted the cd1 then all went automatically.
I appreciate any help. Please.

Nancy-Drew Legend Of The Crystal Skull

It seemed like it could have been a documentary at times. Maybe it was based on a true story?

As the bolts of power are entering her head, at the end, she says “I finally know what it means. It’s _____ !!
What word is that?
Thanks

Does anyone know where a screenshot of the case of glass eyes is? It would be much appreciated! Thank you in advance if anyone can find one, because I sure can’t!
