I've come across trying to install some applications which simply don't want to uninstall via the Programs and Features section of the Windows Control Panel. Well the good news is that there are coders out there that are smarter than Microsoft that developed a really useful application that intelligently scans the application you want to uninstall and remove it from your computer. This comes in handy when trying to uninstall adware from your PC as well. The name of the application is Revo Uninstaller that there's a free version that does the basics. It saved one of my computers so far.
