hey guys. seems i have a problem

whenever i try to install either of the two action replay softwares, i get an error stating that "c:\\WINDOWS\SYSTEM32\AUTOEXEC.NT. The system file is not suitable for running MS-DOS and MS Windows applications. Choose 'Close' to terminate the application."
and it gives me two options: close and ignore. i've tried both, but neither do a thing. the installer just exits.
i've tried restarting and junk, but nothin seems to work. is this a prob in my windows or the software? what can i do to fix it?
thanks!
