Error message when you install or start an MS-DOS or 16-bit Windows-based program

Replace the standard version of autoexec.nt/config.nt by copying a backup copy
located in %windir%\repair\ to %windir%\system32\
(NB: %windir% is typically C:\Windows)

Start>Run and type it this without the quotes:
"cmd /c copy /y %windir%\repair\autoexec.nt %windir%\system32"
