Game won't launch?

Can't get game to run. Clicking play does nothing. Anyone have any ideas?

I had the same problem; in my case the cause was the lack of file "mscvp100.dll" (I am assuming your operating system is Windows); if you want to verify if you have the same issue search in your hard disk for the file "NightSky.exe" and run it.

If it says that it needs the file "mscvp100.dll" try installing this:
