ZapMessenger Ã¢â‚¬â€œ the one step tool to completely remove Windows Live Messenger, MSN Messenger and Windows Messenger 5.x. The first thing ZapMessenger will do is attempt to cleanly uninstall Messenger normally and if that fails for any reason, it will forcibly remove Messenger from the Windows Installer engine allowing you to reinstall at your leisure without hindrance.
No installation is required. Please note that the .NET Framework 2.0 or above is required.
