Hello friend, I read some article about this The Sims Medieval video game and now I want to install this game on the system. The configuration of the system is suitable to this PC game. I have been trying to install this video game on my windows 7 based computer system. At the time of installation it gives the CRC error message. That is Cyclic Redundancy Check error message. I need to solve this error message and then successfully install the game on this system. Any help for solving this trouble would be appreciates.
