Downloading and installing went extremely smooth. My licence was recognized with no problem. The program quickly started and I tried "Cleaning and Fixing" as a start. The setting was in default mode. The "finding" went fine --- then it FROZE when I clicked on repair. No slider control, no menu control, just the (no response) message on the top line. Using the red box to close the program Windows gave me the choice to close or wait a bit longer. This would amount to 20 minutes, total waiting --- giving JV16 the benefit of the doubt. I finally closed the program, waiting for a long error report to upload to Microsoft. Then I reset (restarted) the computer and tried again. It froze again.
I didn't try anything else. Never has this ever happened before.
