File not on control panel



I went to install AnyDown and would not open using Live Mail,(I have it on a disk) got the error message WLDLOG.DLL is missing or corrupt, Googled and Microsoft instruction’s were to uninstall and re-install Windows Messenger in Windows Essentials, go on Control Panel and Iobit Uninstall and its not on either, but is in program files on C:/. How the heck do I uninstall this thing? T.I.A.
