I downloaded a trial version of Lightroom. The Creative Cloud app downloaded and installed just fine but when I try to open lightroom I get an error code 21 "Errors encountered during installation". When I go to the Adobe trouble shooting page they do not list error code 21.

    I tried searching for the file and could not find it.  "more information" is useless.  Not sure where they store the installation log.


    I finally gave up trouble shooting, Uninstalled the CC app and then reinstalled it. After reinstalling the CC app the Lightroom app then installed and is now working.

    Got same error after multiple tries to install Lightroom CC.  Tried installing to a new drive. Rebooting computer. Rebooting CC. Nothing works.  Click "more information,"  and the html file is blank.  Also tried manually deleting LR 5. Tried to install another adobe app from CC and no problem.

    I see chat is off line. and the phone support, typically awful, is dreadful now.

    Adobe, not ready for prime time.

    The "more information" button opens a blank screen that after 5 minutes remains blank.
