I hope someone will be along soon to move this from the Photoshop forum to Installing Flash Player
But mean time you could confirm that you have applied for, and received, a license for redistributing Flash Player.
Also, what do you mean by "using distribution list"? What do you want to avoid?
Thanks for your reply.
I don't to use re distribution license. I want to know is there any way to install flash player on closed environment with out using distribution list.
It is a license violation to install it for others without a redistribution license, I understand.
Please go through "Background updates from an internal server" topic available in http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/devnet/flashplayer/pdfs/flas h_player_26_0_admin_guide.pdf for detailed description.
