    Lightroom 6.5.1 Update Failures

      Today, I was using LR v6.5.


      Moments ago, I tried to update to v6.5.1 but I got the following screen.

      The error log reads as follows:

      Lightroom CC/6 Update – April 2016

      Installation failed. Error Code: U44M1P7


      As a result of the update failure, Lightroom does not recognize raw (.nef) files created by my Nikon D5.


      Before I started the update, I was using v6.5. Now, LR System Info shows that the failed update has moved me back to LR v6.0

      I tried the update process again but it continues to fail.


      I'm using a iMac computer with up to date MAC software. (Mac OS-X El Capitain v.10.11.4).

      Lightroom is up to date as of today-- Lightroom version: 6.5 [ 1067055 ].
