I get an error message on my laptop when trying to load certain software. I don't get this error on my other computer with the same operating system, so I'm confused. The error message that pops up is "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." The software I'm trying to run is "Critters" and "Winnie-the-Pooh" storybooks for my son. What's causing this error message, and how can I fix it?
