I also got an error unzipping the game but was able to open it, and then got this
XAudio2.7 is not installed. Make sure you have XAudio 2.7 installed. XAudio 2.7 is available in the DirectX End-User Runtime (June 2010).
I did play it and I couldn't figure out how to progress, it tells me I need the book and sarcophagus but I'm pretty sure I picked them both up?
