The icon you posted is not the default 7z icon. It's what windows shows when it doesnt have an icon for the program of the icon is broken. I have gotten this on my W7 pc once and it was a problem of the settings being changed while not running the program as an admin. So the first thing I would do is to go browse out to the root of the 7z program and run that as administrator. make your changes and see if that helps. If not you might follow one of these guides that I found with a simple google search.
