The NTVDM CPU has encountered an illegal etc. etc.

I just got a new PC, it's an older Windows XP Professional with Service Pack 3.

When I try to run the TNM installer, I get this:

16-bit MS-DOS Subsystem
TNM7SE.EXE
The NTVDM CPU has encountered an illegal instruction.
CS:0549:IP:763b OP:ff ff ff ff ff Choose 'Close' to terminate the application.

Anyone have any ideas? Am I not gonna be able to run TNM on this machine since it's SP3?

Additionally, how can I check to see if this is the 64Bit XPP or 32Bit? I'm assuming that's part of the problem and that it's probably 64Bit.

Try right clicking on My Computer -> Properties.

That works in Vista and Win7; not certain if it will tell you in XP too.

GOD I'm a douche. I didn't figure out till later that the old PC was too old and slow for the new flashdrive I got. It kept cutting off files halfway through, even though it showed up on the drive as being the full file. The TNM7SE Installer I was using was just corrupted, it wasn't the OS at all.

Moved a new installer over, plus a pre-existing TNM install, using an old flashdrive I had, and everything works fine now.

Huzzah.

P.S. Welcome back.
