Dear Tony, I try to download the link but I get this error again: You don't have permission to access "http://fpdownload.adobe.com/get/flashplayer/current/install_flash_player.exe" on this server. Reference #18.1254ddc2.1286212039.f6f4e1 If you can download this file please send me the IE and Firefox version to d44143@gmail.com

Thank you very much for your direction,please help me.

Solved Solution:

It's happen because you are in the country like Iran. It's seems that Adobe or maybe Iran government filter some IP. do following tasks:

1. you can download it from this link : [ http://www.4shared.com/file/S-K6vU4E/flashplayer-win.html] (you can search 4shared.com for future updates)

2. use a anti filter like ultrareach to direct download from Adobe site.
