No Error - Disk Won't Run.

If the disk does not run but gives no error message then try:

• DRM - DRM will usually generate an error message but it does not always. Look here.
• Does the PC meet minimum spec, is it generally in good shape?
• Is the system language 'English (United Kingdom)'?
• Is the disk clean and scatch free?
• Does the disk run in another computer? If it does then go through the DRM fixes.
• Try compatibility mode.
• Try running the disk in Safe Mode.
