If that fails then and only then would I consider use of say REVO UNINSTALLER.
If you need an authoritative answer, you need to call the software's author.

I want to download and install the latest windows messenger.I wanted to uninstall the version I have now first(version 4.7) but its not in my add/remove programs list and there is no uninstall from the start menu.If I download and install the newest version will it just replace the one I have automatically? Thank you
