Not usable. The display and explanation show an interesting program; however, once installed with the license, it simply does not work. Whether you open it simply or run it as an administrator, it always starts with all the details of the recovery drive. If you try to switch the highlight to the C:/ drive, you get the message “computing resources size, please wait” and the program freezes. Tried patiently a few times but always end up with the same response. Actually after another few tries, it finally started but it takes so much time to start that it is very frustrating to use.
