Goes to the previous page from what? We should not allow to go to the confirmation page back from the "download and install" page.

> Installer detects existing tools on confirmation page. If after that a change happens (like the user uninstalls VirtualBox) and then the user goes to the previous page and to confirm page again - the change is correctly detected, but instead of replacing the old option, there are now both options for 'install' and 'use existing'. Plus the count of detected components stays the same.
> Using the existing (no longer existing in fact) installation fails, naturally.
