I deleted a mongoDB folder and always reported an error when installing it again. Arguably, it should be because mongoDB has not been unloaded cleanly. However, mongDB cannot be found in the uninstallation program. If you want to uninstall through the uninstallation program of the computer manager, you cannot find Mongdb either. What should I do?
Try clearing the registry with ccleaner.
When deleting, just use GeekUninstaller directly, which is much better than housekeeping.
