Q:  Every time I try to run the program, it gives me an error that says:
        
            "C:\WINDOWS\SYSTEM32\AUTOEXEC.NT SystemFileCannotRun MS-DOS" or: 
            "C:\WINDOWS\SYSTEM32\CONFIG.NT 
        The system file is not suitable for running MS-DOS and Microsoft 
        Windows applications. Choose 'Close' to terminate the application."

    It then gives me an option to either 'Close' it or 'Ignore' it, but when
    I click on one of them nothing happens. I've also tried re-installing it.
    My operating system is Windows XP. I hope you can help me.


A:  This is a Windows problem that is caused by upgrading to Windows XP SP2
    (Service Pack 2). Apparently, in some Systems, during the SP2 installation
    important System files such as: AUTOEXEC.NT or CONFIG.NT get deleted, 
    causing various Applications to fail and yielding the above errors.    

    The same issue has been reported to also happen after a virus attack 
    that is messing up people's System files and it is just running rampant.
    In order to protect your System, please make sure that you have the 
    latest virus Definitions installed for your anti-virus software program. 

                                   ***

Please see the following from Microsoft's Knowledge Base regarding your
    Windows error message:

                                   ***

You may also try this:
    Sometimes Windows may back up the file AUTOEXEC.NT in the Windows/repair
    folder from its original folder of Windows/System32.
    See if you have it there and if so, you may just copy it back to the 
    System32 folder and all should be good.
