Hi,

I have just installed a fresh copy of SP2 on my new Pentium dual core
PC, and when I try to run regedit I get a window titled something like:
16-bit MSDos subsystem with an error "NTDRV CPU illegal operation" (or
close to that).

Also, some of my exe's won't run at all. There seems to be no logic to
which will and won't.

I also use a dongle protected music program which has some of the same
errors in the installation of it, and then runs, but immediately causes
an error and closes.

Can anyone help?

Thanks,

Martin
 
Hi,

Hopefully the dongle is XP-compliant, many older ones that rely on direct
hardware access are not.

As to the error message, close all running programs. Locate ntvdm.exe in the
\Windows\System32 folder and delete it (it's probably corrupt). Reboot the
system. See if the problem goes away, as the file will be replaced by one
from the system cache (System File Protection at work). You may also want to
do this with wowexec.exe, as this is another file that supports the 16-bit
subsystem.

Thanks Rick. Will try that.

AFAIK the dongle is XP compliant - I was using it on my old machine
which was SP1 and I know of hundreds of users on SP2 who haven't got
problems (it's a SynchroSoft dongle for Cubase)

Will report back soon,

Nope. Even the clean install would not run regedit - it was the first
thing I tried before I changed or installed anything...

It will be hard to take the disk back to the shop because it's in
England and I'm in France. I can do it in a couple of weeks, but I need
a working system until then. Can I replace any files with the SP2 update
downloadable from MS, even though I have uinstalled sp2...?

Hi Martin,

If a clean install still produces problems, you may have damaged hardware.
Are you sure you just didn't do an "over the top" installation?

Sorted - my system disk was damaged (in transit I assume). Installed a
new one and all working perfectly (apart from the BSOD
"IRQL_NOT_EQUAL_OR_LESS" or something like that, but I think that was my
old USB hard drive... I've had it on another PC when that was running :-)

Thanks!
