Windows 7 (x32) update fails on
Adobe Flash Player 32-bit Plugin 184.108.40.206
Adobe Flash Player 64-bit Plugin 220.127.116.11
with error codes 6BA and 80070661.
Hangs in my update center since November 2011.
Feel free to ask for any details.
That is very interesting - I didn't know that!
What I would do is update Flash Player manually; you can download the installers for 11.3 from http://helpx.adobe.com/content/help/en/flash-player/kb/installation-pr oblems-flash-player-windows.html#main-pars_header
However, many users have experienced problems with 11.3, so I would recommend to download the safer version 11.2 from forums.adobe.com/message/4506372#4506372
Still, I am going to look into what could be causing that error 80070661.
- in Opera and FF flash version is 18.104.22.168
- in IE there were no flash plugin at all , so I've installed latest - 11.3.300.257
Still the same "Windows Update encountered an unknown error".
b.t.w. 6BA (0x000006BA) code is for 32-bit version and 80070661 (0x80070661) is for 64-bit.
And I've tried Microsoft FixIt. To no avail.
 now I have no clue, how it happened to appear in Win Update,
though I could have updated IE from 8 to 9 at some point before November 2011,
and plugin got lost in the process (?)
By any chance, are you on a corporate machine where you don't have administrative rights? If not, then the following should help.
I would try the following:
1.) Close all open applications
2.) Go to Start > Control Panel > Programs and Features
3.) Uninstall Flash Player
5.) Download Flash Player from here: http://get.adobe.com/flashplayer
You'll need to do this once for Internet Explorer, and once for Firefox/Opera
If installation is still failing after that, please let us know and we'll help you troubleshoot further.
Update4: Most likely the problem is on our side, see my post below.
Thanks, Jeromie, it has worked. [see update below]
However, it would be interesting to know what gone wrong and how could I prevent this.
Also, I don't know how Flash updates work, but it would certainly be good, if I could update from my Windows Update server.
Consider my company: most users (about 250) have weekly internet-traffic limit of about 50 MB (no problems with bandwidth, only to force people not to visit entertainment sites).
Hence, most users will ignore Flash Player updates, just to save few precious MBs.
Errors have returned few hours later after reinstall .
I've noticed that update process passes "download" and "creating recovery point" phases,
and error occurs on about 30% of installation of 32-bit plugin update.
If you'll point me at some system log, I'll be happy to provide more info.
Maybe the problem is in our Windows Update server ?
 I've unistalled both "Flash Player 11 Plugin" and "Flash Player 11 ActiveX",
maybe I should have also uninstalled AIR ?
Edit2 I've uninstalled both and then rebooted once. Maybe I should have rebooted
after each uninstall (i.e. 2 reboots in total) ?
