Question about Microsoft Windows XP Home Edition

Ntvdm cpu encountered illegal operation Hi all! I just installed Maya 2010 from a torrent file and since then I got this famous error message. It's just appeears as three command prompts appearing at the startup of the computer (at the desktop startup of course) and the error message for every prompts: Heading: 16 bit MS DOS downsystem Path: C:DocumentpcstartProgramAutostart(And here lies three installation files that keeps bugging). Message: ''NTVDM CPU encountered illegal operation.'' This has come up since the day I installed Maya 2010. It was for a 32 bit computer, not a 64 bit installation. During this installation, the wizard offered three options and one of them was ''Add to System Path'' (which I guess thats a reason to the problem). I been looking around forums with the same problem and I think that the three installation files with 32 bit is trying to pass to the 16 bit territory. I think thats the problem but I don't want to to any more mistake beacuse I have brought every method I could to get rid of this (I have even reinstalled Maya by clicking on the Maya installation icon from the torrent file. Have deselected the Add to System Path but doesn't get rid of the problem). Any solutions? If you wonder more or you don't understand please ask me to clear thing up or explain more. Richard

    Hello jigarbhati

    Im sorry it took so long!

    If you have the same problem as me and if your sure it was maya that caused you trouble, then search the file(s) that causes you trouble. And delete them.

If I am reading this right your issue is not the application but where you obtained the application. Maya 2010 is a modern design application and comes in 32 & 64 bit versions. It is not a 16 bit application.

When Windows encounters a legacy application it calls the NTVDM for the legacy application to run in.

The fact that the application is calling the NTVDM is highly suspicious. NTVDM is the NT Virtual Dos Machine, a way for legacy applications to run in NT environments.

NT environments are Windows NT 3.5, NT 4.0, Windows 2000 Professional, Windows XP (Home, Pro & Media Center Ed), Vista (all versions) and Windows 7.

Old (legacy) applications written for 16 bit date back to Windows 3.1 and include Windows 95, 98 and Millennium Edition.

I would obtain a copy of Maya 2010 from a reputable outlet instead of Bit Torrent as "warez" frequently contain malicious items that will infect and ruin your machine.
