I have tried to install MySQL latest version on Windows 10 on 3 computers but all have given an error during configuration. After this double-clicking the MySQL icon leads to either a black window (command line) opening with the prompt "MySQL-js" OR if I click the item "Command Line Client" under the options that open by clicking MySQL main item under apps, a black window (cmd??) opens for a split second and disappears before I can even read anything on it!
Below is the dialog box that is the point at which the installation stops, and a copy of the log file (from the attempt on the last PC).
