Data Error (cyclic redundancy check)
(0x17)'

It happens in random spots each time i try to install the game. Yes, it is a legal copy i bought from Walmart for fifty bucks. Yes, my computer does have the right specs to play.
This error seems to mostly come up 3 quarters and more of the way into the installation, and it seems to mostly happen with the .htm and .gif files. :[
