There is something wrong with the download that Adobe is pointing too. You can get the working download here:

http://fpdownload.macromedia.com/get/flashplayer/current/licensing/win/install_flash_player_10.exe

That solved my problem immediately.

I got this info from this post on the Adobe forum:

Flash Download Problems

WindowsXP SP3

Mozilla/5.0 (Windows NT 5.1; rv:6.0.2) Gecko/20110902 SeaMonkey/2.3.3

(Note well: Internally, SeaMonkey 2.3.3 is the same as Firefox 6.0.2. They both use the same Gecko 6.0.2 for rendering Web pages, interfacing with the Internet, downloading, etc.) They differ only in the user interface (menus, buttons, etc).

I see two problems when trying to download a new version of Flash Player from http://get.adobe.com/flashplayer/. .

1. Your Web server is sniffing for my browser. I select the "Download now" button, and I get the same page all over again. The navigation is looping. If I spoof Firefox 6.0.2, however, I do get a download. This means you are sniffing for "Firefox" when you should be sniffing for "Gecko".

2. While spoofing Firefox, the download gives me install_flashplayer10_chrd_aih.exe, which is not the installer for Flash Player 10.3.183.10. Instead, it is some kind of helper. To get the correct installer file, I had to search my archives to find the URI http://fpdownload.macromedia.com/get/flashplayer/current/licensing/win /install_flash_player_10.exe.

Both of these problems were previously cited in this forum at http://forums.adobe.com/message/3885371. Neither problem has been fixed.

Thanks for the link. I tried it but got the same result. I finally realized that the Adobe Flash plug in was disabled, along with a lot of other plug ins. If anyone is having this issue, be sure and go to your Firefox plug in management and enable whatever you need to. The default for the upgrade to 7 apparently disabled them all.
