To disable Protected Mode, add the following line to your mms.cfg file located in:Windows 32bit: C:\windows\system32\macromed\flash
Windows 64bit: C:\windows\syswow64\macromed\flash
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.
