So I'm not sure if this has happened to anyone, but I've had Windows Mail and Movie Maker installed on my computer (Windows 7) and I uninstalled Mail because I got Outlook. I did this using REVO uninstaller (which removes all files leftover) but I must have turned my computer off during the process or something stopped it working fully. The outcome is that Mail as a program on the taskbar is still there but I can't use it because of a missing WLDCore.dll and Movie Maker for some reason has disappeared. So I thought to uninstall it again, but it's not there. I then went to install it again and so I selected the 'Choose the programs I want to install' option but it said Mail and Movie Maker is already installed. I've looked everywhere on my computer for the files and can't find anything. I decided to download Windows Live Messenger so I could uninstall it and hopefully kill-off some of the leftover files of the other programs, but after clicking on it, it says missing wldlog.dll and it's the same story as the Windows Live Mail (even though I've just installed it).
