chewtoy 0 Posted January 4, 2005 If this isn't a clue to buy a new printer I don't know what it is!!!! I'm trying to get my dad's printer to work. It's a cannon C555 multifunction. I'm trying to install the software and drivers from the install disk, and I keep getting the error : c:\winnt\system32\autoexec.nt. The system file is not suitable for running MS-DOS and Microsoft windows applications. Choose "close" to terminate the application. I found a fix for the error on another forum that told me to find the "autoexec.nt" file in the "repair" folder, then copy and paste it into the system32 file. DIDN'T WORK. Now what? Hope to hear from you soon!!!! Share this post Link to post
