I just install Adobe Flash Player 11 on my Gateway desktop running Windows 7 Ulitimate at 1.60 ghz. The minium requirments are 2.33 ghz for desktop and 1.60ghz for netbook. My Youtube site has stopped playing videos as well as all other video sites. google say error 5. Firefox my image assistant says "Failed to instantiate Image Assistant back-end! You are probably missing a dependent library". But is their any way I can get back the older version?
Here's a FAQ that walks you through the process of reverting Flash Player. However, I'd recommend trying a clean install first.
