  1. Hello all,
    This is my first thread posting. I am having a similar problem that was reported earlier on your message board concerning an error message that consistently keeps popping up, named "16 bit MS-DOS Subsystem". The message is below:

    The NTVDM CPU has ecountered an illegal instruction.
    CS:0dc0 IP:01d4 OP:63 68 65 2f 31 Choose 'Close' to terminate the application

    I have tried to do everything that was instructed by howard_hopkinso's posting ( and now, I'm at the last task where I need to post my hijackthis.txt file as an attachment, for which I've included the file with this thread.

    Any help is greatly appreciated!!!

    Reply to howard_hopkinso on "h91746.exe" error

    I have completed all the instructions in your thread. Attached are the Look2Me-Destroyer.txt and hijackthis.txt files, as instructed by the link:

    Shortly after I rebooted my PC into normal mode, the same "h91746.exe" error message popped up again on the screen. So, is this all that needs to be done to solve my problem?

    Appreciate your time and help!!!

    Boot into safe mode and turn system restore off.

    Let HJT fix all your 016 DPF entries.

    Also fix all 018 entries.

    Fix this one O20 - Winlogon Notify: winupx32 - C:\WINDOWS\SYSTEM32\winupx32.dll

    Run HJT and click on the config button, then on the misc tools button. Click on the dlete file on reboot button. Browse to C:\WINDOWS\TEMP\h91746.exe and click open. You will be asked if you want to restart your system. Click yes.

    The file should be deleted.

    Turn system restore back on.

    Regards Howard :)

    Still not working ...

    After completing all your instructions, the same error message is still poppng up after deleting that .exe file and rebooting my PC, although I have to admit not as often as before. Is there anything else you can recommend to fix this?
