hmm.. In some cases, when you click ignore, the program runs properly, but you continue to receive the error message when you start 16-bit programs.
but i think there are files that damaged or missing on your pc like : · Config.nt / Autoexec.nt / Command.com. what can i offer is try to download this
http://www.softpedia.com/get/Tweak/Syst ... -Fix.shtml and see if its working or not. your case kind of rare, we rarely seen someone having this problem.. well after you try it, get back to me here and see if you make it or not

good luck ^^
