I am on OS X 10.8.4, Photoshop CS6, ACR 8.1.
The "A" icon on my menu bar shows 1 update available.
When I open the CC updater, it says Photoshop CS6 is up to date.
When I open Photoshop CS6 and go to Help/Updates, it shows "Photoshop Camera Raw 7 0.0KB". Note the 7 not 8.
When I click "Update", I get "Adobe Application Manager quit unexpectedly". Following are the first few lines of the dump. Is there a way to get past this?
Thanks for the help!

Thanks to Andrew_Hart for posting the direct download links to ACR 8.2. I direct downloaded and installed ACR 8.2 for CS6. That solved my problem.
I had this same problem with Photoshop CC help/update. When I added */adobe.com to my security exceptions it worked and found ACR 8.2.
