The plugin page shows that message automatically if it doesn't detect a Flash plugin and your system details list doesn't show the Flash plugin.

Do you see the Flash plugin on the Tools > Add-ons > Plugins page?

I see a blank grey rectangle where the movie should be.

I misunderstood you. No, I do not have the Flash plugin at all. My problem is that Firefox and Adobe are confused about which version is the correct one for me...

Firefox's Plugin Finder Service :- Attempts to assist me in installing 11.1.102.62, which fails because Adobe doesn't provide it.

helpx.adobe.com/flash-player/kb/find-version-flash-player.html :- Lists 11.1.102.62 as the current player for Windows.

www.adobe.com/software/flash/about :- Lists 11.1.102.63 as the correct player for "Windows Firefox".

get.adobe.com/flashplayer :- Automatically provides a download of 11.1.102.63, stating that this is the one for "Windows 64-bit, English, Firefox".

You are probably installing the x64 version of Flash, which won't work with Firefox since it is a 32-bit program. Download and install Flash from http://fpdownload.macromedia.com/pub/flashplayer/current/licensing/win/install_flash_player_11_plugin_32bit.exe, and see if it works.

Thanks! That .exe installed 11.1.102.63 correctly, which has solved my problem.

As my screenshot shows, the download I was using before was claimed to be compatible with Firefox on a 64b system, so the cause may be Adobe's failure to produce a functional multi-architecture product.

I have uninstalled the 64-bit and installed 32-bit version of Flash but still the problem exists.

BTW, the 64-bit version of Flash includes both 32 and 64 bit versions. So this could not be the problem. Please advise.

hardwarecrazy,

You're right that Adobe's 64-bit Flash installers include both 32 and 64-bit Flash versions. Ref: http://forums.adobe.com/thread/909550

There are two separate installers, one for IE and another for Firefox (I installed both on my 64-bit Windows 7 computer). Here are the download links I used, for the latest versions (currently 11.1.102.63):

• Direct link to current 64-bit plugin version (for Firefox) http://fpdownload.adobe.com/get/flashplayer/current/install_flash_player_64bit.exe

• Direct link to current 64-bit ax version (for IE) http://fpdownload.adobe.com/get/flashplayer/current/install_flash_player_ax_64bit.exe

(The above links are from Adobe's Installation problems help page, HERE.)

If you need more help, you should ask a new question since this one is solved.
