✔ Best Answer
Flash Player 11.8.800.133 is an out-of-date version so try updating it from their website using Firefox. Latest version is

In Firefox, Flash Player runs as a plugin, whereas in IE it runs as an ActiveX control.
That's why it often works okay in IE when it won't work in Firefox.

I gave up on Firefox when Flash Player kept crashing, it's a common problem.
Now I use Google Chrome which comes with Flash Player built-in, and it updates itself automatically. No issues at all with it.

Dear All,

This error is just because of the installer. I was installing flash from debug offline installer. I just simply uninstall it and install from a standard installer.

Thank you all for your kind support.
