I'm using Win8 pro. Due to unknown circumstances the regular start icon for IE has disappeared from the desktop. I found it in all programs, but when I try to run it I get the following: The NTVDM CPU has encountered ab illegal instruction than a numeric code. Close to terminate the application. I tried to reinstall but it gives me a message that I already have a later version installed. Tried to remove and than add from windows--it didn't work. Basically I can't use the program. Please advise.
