How to Force enable, silent updates for Adobe flash in windows 8

How to Force enable updates, silently for Adobe flash in windows 8 using group policy?

I have followed this Article:

http://helpx.adobe.com/flash-player/kb/administration-configure-auto-u pdate-notification.html

http://gpyall.com/archives/disable-adobe-flash-updates-on-64-bit-windo ws-with-group-policy/

This looks promising but not working.

Also, I cannot even manually create a file, in Win 8  (C:\Windows\SysWOW64\Macromed\Flash)

So how would group policy can put mms.cfg in this location with following vaule:

SilentAutoUpdateEnable=1

Thanks in Advance.
