Chromodo version 48.12.18.238 fails to install

I tried to update Chromodo to version 48.12.18.238 three times, but it keeps failing (attached is a screenshot). My operating system is Windows 7 Pro SP1.

Solution found. Temporarily changing the Windows software restriction policy security level from disallowed to unrestricted allowed Chromodo to update. Never had to do that before.
