I too have simcity 3000 and played it on my old computer, but now I have Windows XP, and when I go to install the game I get an error message of "C:/windows/system32/autoexec.nt. The system file is not suitable for running MS-DOS and Microsoft windows applications. Choose close to terminate the application." I have read all the tips on this page, but I do not understand how to copy C:\Windows\Repair\Autoexec.nt to C:\Windows\system32. to the root. Can anyone give me a walkthrough on this? Please!
