Ok first off I got this game for christmas, and managed to talk my way into getting it a day early. I went to install it today and the auto play starts i click install halflife 2 then the screen comes up saying its prepairing instillation. Then a box with this message pops up,"This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package." I have contacted them and the advice they gave me was stupid and a waste of time. I tried searching steam forums, knowledge base, VUgames support knowledge base and every thing I can find on the web. I AM STUCK, and on christmas even which sucks because this is basically the ONLY thing i said I wanted. So if anyone could please please please help me with this I would be greatful.
