How can I upgrade it because when I try to install, it says that there are conflicts with the previous version. Is there way so that I donot loose the data/software within version 3.2 and still able to upgrade to version 4.0. Thanks. Mir </blockquote> Hi, I think I just uninstalled 3.2 version of VirtualBox and then installed version 4 of VirtualBox. (my virtual machines remained after this) Jesse </blockquote> </div> That's what I did. Uninstall 3.x.
