windows live mail won’t function; uninstall can’t be done but I need to re-install it!

windows live mail program is not functioning on my wife's laptop... when trying to run it, we get warnings that the wldcore.dll and wldlog.dll are missing... when I attempt to uninstall it, it is not listed in the 'remove program' list, yet when we try to reinstall it, we're told that it can't because portions are already there... I've tried the uninstall from cmd parameter option, as well as the wlarp.exe suggestion, but with no results... I actually copied the "Shared" folder from my laptop to my wife's, which then re-created Windows Live Essentials in the control panel uninstall list, so we uninstalled it that way, but when we try to reinstall it, we still run into the same problem... 

Any suggestions, anyone??
