Copied the important bits from Adobe link that you need.


Finally, if these problems are blocking you from using Flash Player we recommend, as a last resort, you either revert back to Flash Player 11.2 or temporarily disable Protected Mode. We strongly recommend that Protected Mode is manually enabled once this issue is resolved.



To revert to a previous version of Flash Player, please see this FAQ: How do I revert to a previous version of Flash Player?



To disable Protected Mode, add the following line to your mms.cfg file located in:



Windows 32bit: C:windowssystem32macromedflash

Windows 64bit: C:windowssyswow64macromedflash



ProtectedMode=0



If the mms.cfg file does not exist, create one using any standard text editor (e.g.. notepad)



Depending on your operating system, you might need to first save the mms.cfg file to a writable location (such as your documents or desktop folder) and then copy the file into the destination folder using Windows Explorer.



To re-enable Protected Mode, simply remove the line from the mms.cfg file.




IF YOU GET REALLY STUCK A VIDEO BELOW WORKING YOU THREW IT.



There is even a video here on youtube showing how to disable Protected Mode in Flash Player Plugin.
