I find if an older game or program cannot be installed by way of the CD then use "Program Compatibility Wizard" to install it. If the game is installed, but will not start by way of the CD, then when inserting the CD hold down the left Shift key for approx. 15 sec. to keep AutoRun from taking over. Now click the game in the "All Programs" list. Should start. --------------- From a Microsoft web page: If an older application gives you trouble when running Windows XP, you can set the compatibility properties manually so that the program runs in a different mode, such as Windows 95, or in a different display or resolution setting. To set the compatibility properties for a program: 1. Right-click the executable or the program shortcut to the executable, and then click Properties. 2. Select the Run this program in compatibility mode check box. 3. From the list, select an operating system that the program runs in comfortably. 4. If necessary, also change the display settings and/or resolution, or disable the Windows XP visual themes. Run the program again when you?re finished changing the settings. Adjust the compatibility settings again if the program is still not running smoothly: a program that's unhappy on Windows 2000 may flourish on Windows 98. --------------------- How to Troubleshoot Program Compatibility Issues in Windows XP http://support.microsoft.com/default.aspx?scid=kb;en-us;Q285909
