I have installed Flash player 11.4.402.287 on a "fresh" PC, moments after installing Windows, drivers, directX etc. After installing Flash Player Firefox totally hungs immediatly after run.

First page (adobe page, because it was launched before closing firefox) doen't load. I see new tab but FF goes hung to zero-responsivity, even loading icon stops in single position.

KMPlayer, wich uses firefox also hungs.

How to solve this issue ?

Can you provide any more details to assist with troubleshooting the problem? – Sylvester the Cat Oct 29 '12 at 22:47

Try disabling protected mode of Flash Player and restart the computer. If that does not fix the issue, then re-enable protected mode and try something else.
