16 bit ms-dos subsystem error while creating android emulator

Issue

- Everything was working fine till the electricity went off.

- After the electricity came back and i switched on the computer, i am getting this weird error as i am trying to start or create the Android Virtual Device in the Android Virtual Device Manager.

Can anyone please let me know the reason for such an occurrence or any possible way to restore this back.

Solution

Sounds like some part of your 16-Bit subsystem was corrupted. I found a quite comprehensive troubleshooting-guide here: http://support.microsoft.com/kb/q196453

If that doesn't help have a look here and try whatever these guys found: http://social.msdn.microsoft.com/Forums/en-US/e5466e39-29b2-4667-96c4-6bacd8a397d4/the-ntvdm-cpu-has-encountered-an-illegal-instruction-error-message-pops-up-when-installing-visual?forum=vssourcecontrol
