You may need or require, a service update pack of the Os first if windows 7 Sp1 or Sp2 if not installed or downloaded and installed by windows update service.
The next thing to check is if direct X is installed and is a up to date version.
You may also need to install what we call the dot Net frame work for windows prior to the install of the game.
As the installer may require it. without it, it can throw errors up when installing a game or application. It would also help if you could tell me what graphics card or graphics chip you are using.
Try to update the Video driver software if you have not done it in a long time for the graphics card. Do all of these before you attempt to install the game. If it works then apply the patch for the game after it. The last thing could be down to the permissions set in windows, so right click on the install Icon or exe of the game install, and select run as administrator. See if it helps Other than that I would put it down to a scratch on the disk, or the Dvd drive not reading the data of it for the install to the Hd of the computer if it is an old Dvd drive.
