When I removed Renegade X, I deleted the files manually (removed them from the folders to the recycle bin). I believe my system still thinks there's a file on the drive by the name 'Renegade X Installer.msi' (which was deleted after moving to recycle bin), which explains why 'Renegade X' is still in the Apps & Features Folder. When I attempt to uninstall it, the process still looks for the original (now deleted) files. I believe the best bet is to either find the original installer file and put it on my drive, or recover it from the deleted recycle bin (of which I'm not technically savvy enough to do).
