Whenever I try and use the "regedit" command from the run line in the start menu using Windows XP I get the error that says "The NTVDM CPU has encountered an illegal instruction. Then a line of letters and codes and it says to choose 'close' to terminate the program." If I choose close or ignore it closes anyway.
The only help I have found was at Microsoft.com and it was talking about using the install disk and going to the run line and inputting another code. Well, my computer came from a rent to own place and already had XP installed. So I don't have the install disk.
Any help would be GREATLY appreciated!!
Here is a screen shot of the error:
