An error occured in help menu

An error occures when I try to make F1 to see the help vudeo of a command.
It is happen to appear when I click on the little video to start.
Even though there is a security warning, I downloaded Adobe Flash Player,
yet it doesn’t help. Same messages appear.
Can you please help ?

Your best option is to use the Help file through an Internet connection:

Thank you very much for the link.
Actually I found it very useful to use F1 option through working on a file…
