VirtualBox Install

I’ve been having an issue with VirtualBox. I tried to update to version 6, and it hiccuped and broke the app. I tried to do a complete uninstall, following instructions from various sources, then a reinstall after downloading a fresh install file for version 6.0.10, but nothing seems to work. It begins the install, then right away a message pops up saying the older install of version 6.0.10 cannot be removed, with a fatal error message. I’ve attempted to remove every mention of VirtualBox from the system, including a registry search, but to no avail. I’m hoping someone here may have run into this same problem and found a solution. My OS is Windows 10 Pro version 1903. Any ideas, anyone?
