Yes, the installation process can completely roll back when installing Rumba+ in any configuration using the Setup wizard. It undoes every operation it performs during an installation, modification, repair, or removal. This is particularly helpful if you encounter a fatal error during an installer session. The computer can return to its previous state before the installer session. This includes restoring deleted or overwritten files, registry keys, and other resources. 

Note: You cannot roll back a completed Rumba+ installation; you must uninstall the program to remove it.
