When you install a 16-bit bit program on a computer that was upgraded to Windows 2000, you receive:
Application popup: 16 bit Windows Subsystem : An application has attempted to directly access the hard disk,
which cannot be supported. This may cause the application to function incorrectly. Choose 'Close' to terminate the application.
If the Autoexec.nt, Config.nt, or Command.com had invalid entries, this problem will occur.
To fix the problem:
1. Open a CMD prompt.
2. Mount the Window 2000 CD-ROM in the CD-ROM drive.
3. Switch to the CD-ROM drive letter by typing its drive letter, followed by a :. Example: D: and press Enter.
4. Type cd i386
5. Type:
rename %systemroot%\system32\Autoexec.nt autoexec.old
rename %systemroot%\system32\config.nt config.old
rename %systemroot%\system32\command.com command.old
6. Type:
expand autoexec.nt_ %systemroot%\system32\autoexec.nt
expand config.nt_ %systemroot%\system32\config.nt
expand command.co_ %systemroot%\system32\command.com
7. Shutdown and restart your computer.
NOTE: See tip 1809.
