How do I update PSE 12 and Premiere Elements 12 for ACR 8.5?

Question

I tried posting this earlier, got no responses. Recap as follows:
using an iMac with OSX 10.9.4
From PSE12, used the "updates" pull-down menu, Adobe Application Manager (AAM) starts and indicates that there is an update available for both PSE and Premiere 12.  When update is selected, AAM shows:
   Update Failed
   Updates could not be applied
   The error log file may help you in identifying the problem.  The, try updating again.  If the problems persist, contact customer support for further assistance.
  The error lot file read as follows:
   Photoshop Camera Raw 8.5
   There was an error installing this update. Please quit and try again later. Error Code: U44M1I210
When using the Terminal application to open the updater, I get the following response:
/Applications/Utilities/Adobe\ Application\ Manager/core/Adobe\ Application\ Manager.app/Contents/MacOS/PDApp ; exit;

Any guidance on updating to ACR 8.5 would be appreciated.

Barbara,
Yes, I accessed the "updates" menu from the Help pull-down menu.  I also accessed the updates using the Mac Terminal application with results shown in my original post.  Regardless of whether I used the Help menu or the Mac Terminal app, the AAM tool still responded with:
Update Failed
   Updates could not be applied
   The error log file may help you in identifying the problem.  The, try updating again.  If the problems persist, contact customer support for further assistance.
  The error log file read as follows:
   Photoshop Camera Raw 8.5
   There was an error installing this update. Please quit and try again later. Error Code: U44M1I210
   Looking at the the output of the Mac Terminal app, it shows:
   ... hdiutil: attach failed - no mountable file systems
   Is this relevant?
Regarding your follow-up message pointing to:
Update 12.1 installation errors | Photoshop Elements, Premiere Elements,
the files referenced in this link are present, are correctly named, and they are in the correct locations, so it would appear that these issues are not related to the ACR 8.5 update problem
Thanks
