Function to enable Adobe Flash Player silent automatic update feature
I created the following function to enable the Adobe Flash Player silent automatic update function that was introduced in the recent 11.2 version. KiCHiK's "Replacing Lines in a Text File" example code was very helpful here. I believe you will also need LogicLib.nsh and x64.nsh as includes for this function to work. I tested it with Windows XP (32-Bit) and Windows 7 (64-Bit). Because you are accessing protected system files, you'll need "RequestExecutionLevel" set to "Admin" on Windows 7. I just wanted to share it incase there are other systems administrators that could find it useful. Thanks!

You don't need to have the code twice for 32/64. NSIS is 32-bit so will always point to SysWOW64 on 64-bit Windows and System32 on 32-bit Windows when you use $SYSDIR (unless you disable file system redirection using the macro in x64.nsh).

from my view - code that none needs - as you pointed out to adobe blogs the updater has itself this option.
and 11.2 is present version. eot

Thanks for sharing. But next time please use an attachment or pastebin for something this big. :)

Afrow UK - You're right. The code is redundant. Thanks for the tip. :)

Brummelchen - The code allows systems administrators that manage hundreds or thousands of systems to enable this feature automatically. I did not see an option in the native Flash installer to control this feature. The only current methods of enabling the feature, to my knowledge, are via the mms.cfg file and the Flash control panel applet.

MSG - Thanks for the tip on using an attachment. Will do next time around.


Thanks for the feedback!
