    I am running Windows XP with SP2 and when I download programs and try to install them I get a error that says "16 bit MS_DOS Subsystem "at the top of window then it says 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.
    At this point i can either choose close or Ignore and neither option lets me install the software I am trying to install. Note: Has done this on several
    different kinds of programs. What might be the problem?

    Thanks in advance

    try this Open C:\Windows\System32\Config.nt with notepad.

    Erase the entire file contents and make it look like this with out the dashes:

    dos=high, umb
    shell=c:\windows\system32\command.com /e:4096

    Open C:\WINDOWS\SYSTEM32\AUTOEXEC.NT with notepad and make it look like this:

    @echo off

    REM AUTOEXEC.BAT is not used to initialize the MS-DOS environment.
    REM AUTOEXEC.NT is used to initialize the MS-DOS environment unless a
    REM different startup file is specified in an application's PIF.

    REM Install CD ROM extensions
    lh %SystemRoot%\system32\mscdexnt.exe

    REM Install network redirector (load before dosx.exe)
    lh %SystemRoot%\system32\redir

    REM Install DPMI support
    lh %SystemRoot%\system32\dosx

    REM The following line enables Sound Blaster 2.0 support on NTVDM.
    REM The command for setting the BLASTER environment is as follows:
    REM SET BLASTER=A220 I5 D1 P330
    REM where:
    REM A specifies the sound blaster's base I/O port
    REM I specifies the interrupt request line
    REM D specifies the 8-bit DMA channel
    REM P specifies the MPU-401 base I/O port
    REM T specifies the type of sound blaster card
    REM 1 - Sound Blaster 1.5
    REM 2 - Sound Blaster Pro I
    REM 3 - Sound Blaster 2.0
    REM 4 - Sound Blaster Pro II
    REM 6 - SOund Blaster 16/AWE 32/32/64
    REM The default value is A220 I5 D1 T3 and P330. If any of the switches is
    REM left unspecified, the default value will be used. (NOTE, since all the
    REM ports are virtualized, the information provided here does not have to
    REM match the real hardware setting.) NTVDM supports Sound Blaster 2.0 only.
    REM The T switch must be set to 3, if specified.
    SET BLASTER=A220 I5 D1 P330 T3

    REM To disable the sound blaster 2.0 support on NTVDM, specify an invalid
    REM SB base I/O port address. For example:


    You can simply copy and paste from this post into the correct file. Try running your setup program again.
