No don't uninstall using the add/remove control panels. That's a dumb idea. You'll cause problems doing that with a non properly uninstalled program. LW hasn't had that ability using add/remove control panel since about LW version 4.3 which was well over a year ago. You only use the Start menu > Programs > LW > Uninstaller OR
Go to the program folder to find the uninstaller. OR
Reinstall LW & at the beginning of installation it will uninstall the previous version so long as it was version 4.4 or later.
