You will receive an error message that reads something like this:
16-bit MS-DOS Subsystem
path to the program that you are trying to start or install
d:\Windows\System32\Autoexec.nt The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose 'Close' to terminate the application.
Solution?
The easiest is simply inserting the Windows XP CD into the CD drive and clicking start --> Run and entering:
expand X:\i386\autoexec.nt_ c:\windows\system32\autoexec.nt
Replace X:\ with your CD ROM drive letter.
will solve your problem!!!!
