I've just installed this, but I wasn't given the option to click on anything to get it to update automatically in future. Anyone know how to set it up so I don't have to bother re-installing each time? I tried to look for an 'Adobe Flashplayer Control Panel' (as I've read on the internet) but couldn't find it
When you are looking at some Flash content right click on it. In the menu that appears click on Global Settings then go to the Updates tab. You will almost certainly find that it is already set to update automatically. That is the default setting.
