I can't get the right click to bring up settings

I am so frustrated.  this is my tenth time at this page because you keep sending me all over the place.  I have followed the directions for disabling the hardware acceleration because all of my videos are showing in green screen.  When I right click, it only gives me "about adobe"  It is EXTREMELY frustrating.  I am ready to take my computer somewhere and have this player taken off because I can't watch ANYTHING because of this, and your instructions DON'T WORK.  I need to know where I can go in MY computer to change the settings of this program before I lose my MIND.  I have been at this over an hour and your site is just an exercise in frustration!
