I use Uniden Sentinel through Parallels on my 2015 macbook pro retina. Today, everything seemed to be glitching out, so I reinstalled both programs. Initially, Parallels was giving me a white screen, but then it went away. Now when I try to reinstall Sentinel, the screen will flash between white and the windows screen for about 10 seconds, and the program ends up not being installed. What can I do?
