The external disk drive is an LG Slim Portable DVD Writer. My laptop does not have a built-in disk drive, so I purchased an external disk drive which has worked just fine for all other purposes. My computer is a Dell Inspiron 15 with i5 64 bit operating system. They installed successfully, but keep coming up with 'Cannot locate CD-ROM' or 'Program has stopped working' error messages. The games on my now Windows 10 laptop, but the games will not load correctly. Since seeing the game work on my parents Windows 10 computer, I attempted to reinstall and play I attempted to install and run the games when it was Windows 8, but to no avail. My question is I have my own laptop which I upgraded from Windows 8 to Windows 10. (The game was already installed from Windows 7 when they upgraded to 10). Windows 10, and the game still works on their computer even as Windows 10.
They also just recently upgraded their Windows 7 computer to My parents computer used to be Windows 7, and was able to play the game just fine. I own a valid copy of The Battle for Middle Earth II, as well as the Rise of the Witch-King expansion pack.
