I understand from your e-mail that you get the following error message
on your Desktop PC:
"16-bit MS-DOS Subsystem
path to the program that you are trying to start or install
C:\Windows\System32\Autoexec.nt The system file is not suitable for
running MS-DOS and Microsoft Windows applications. Choose 'Close' to
terminate the application. "
This issue may occur if one or more of the following files are missing
or damaged:
Config.nt
Autoexec.nt
Command.com
To resolve the issue, we would need to replace the system files. Use
the following steps to replace system files in Windows XP:
1. Turn the computer on and press the F8 key when the first screen
appears.
2. In the Startup menu, select Safe Mode with Command Prompt and press
ENTER.
3. Wait until the command prompt window appears.
4. Type the following at the command prompt: CD C:\
5. At the C:\ prompt, type expand, then the path of the compressed
system file, and then the destination path. Use the Asterisk (*)
character to represent any character when typing. For example, to
restore all system files that start with mmsystem to the system32
folder, type the following:
expand c:\i386\mmsystem.* c:\windows\system32
To replace the Config.nt, Autoexec.nt and Command.com files, type:
expand c:\i386\config.nt_ c:\windows\system32\config.nt
expand c:\i386\autoexec.nt_ c:\windows\system32\autoexec.nt
expand c:\i386\command.co_ c:\windows\system32\command.com
Note: In Windows XP, compressed system files are stored at
C:\i386. These compressed files have the same filename as
regular system files, but the last letter in their three
character extensions are replaced by an underscore (_).
6. When finished, type the following to exit: shutdown -i
