Windows Driver Package LAUNCH (usbuser) ports (09/20/2013 1.2.0) is in my Programs and Features. How do I get rid of it? When I try to uninstall it says it can't find the .dll. I came here to reinstall and the driver seems to no longer exist.
Try using Revo Uninstaller. Even if it can't uninstall the application normally, it will force it to uninstall by wiping out all traces of its presence from the system.
After that, try running AdwCleaner to make sure that there are no leftover rogue registry keys or toolbars in your system.
You can also use the Force Removal option found in Geek Uninstaller.
