Hy there! Recently I bought an new PC and i have a problem with the older games! The installation doesn't start! I played Dying Light, Wolfenteint: The New Order without a problem! The problem is when I try to install, for example: Prototype, Call of Duty: Modern Warfare 1, Dead Space 1,2 and the list can continue! I have windows 8.1, and recently neither installation of free or old progams doesn't start, but I figure, if a run " the trouble compatibility " , is a chance to run! Please help me! That is pretty annoying! Thanks a lot! And soryy for my english, is not my native language!
