You may be experiencing problems because of some of the processes running in the background of Windows. Too many can interfere with the installation's proper function. To eliminate some of these extraneous processes, you can put your computer into a "selective startup". However some programs may need to be disabled manually, such as your antivirus and other security software.

To put your machine into a selective startup, go to the Start menu, and choose Run. Delete anything on the Open line that you'll find there, and type in the word MSCONFIG. Click on OK, and that will bring up a program called the System Configuration Utility.

Look down the list of startup items (not the tab labeled Startup), and choose Selective Startup (if it is not already selected). If you don't see this, make sure you've clicked on General, near the top of the window. Once you've chosen Selective Startup, uncheck 'Load Startup Items', and leave 'Process System.INI file' and 'Process Win.INI file' checked. Once you're done here, click Apply and OK, and let it reboot your computer.

Your Windows environment may look different and you may get an error relating to your sound device not working (ignore this for now). Try running the installation again. If the game loads and seems to be working, the problem is most likely related to one or more programs you have scheduled to load with Windows. You can then revert the settings back the way they were, and in a trial and error fashion, disable some programs using the startup tab (in the msconfig utility) to try to find the culprit.

If the problem still persists will want to try updating the firmware for your DVD drive. You can find this at the website for the manufacturer of you DVD drive. Also you can troubleshoot the disk by trying to see if it will install on another system. If it does the same thing, more then likely the problem lies with the disk and you will want to get a replacement from the retailer.
