On some NT based machines, a warning message may appear at the end of the installation stating that the AUTOEXEC.NT file could not be found. This file is important for the correct operation of DOS applications. If this error occurs, it is an indication that the DOS portion of the Windows Operating System was not installed properly on the computer. The Borland, 68HC11, and AVR compilers may still function correctly even if this error occurs. The DJGPP compiler will not function if this error occurs.
