This is my first-ever attempt to get support here so I am not even sure I am in the right place.
I own Lightroom 6.0 (non-CC / whatever you call that). I recently purchased a new camera and it will not import the RAW photos. I figured maybe I need an update so when I got the "The files are not recognized by the raw format support in Lightroom. (27)" I tried various things including selecting "check for updates." At that point I got "The version check was unsuccessful." When I tried updating via LR, "Your applications are all up-to-date" appeared. I then went to the Adobe site where it appeared there were various newer versions. No matter which I tried to activate, I got (for example) "Update-April 2016 Update is not applicable. Error Code: U44M2P28." After trying a couple different ones and always receiving similar messages, I am now trying this (although I am not even sure how this works.
I am sure there is something I am not understanding so seek help in what seems to be the only way offered by Adobe. Thanks to anyone who can help with this.
Try creating a new user account with admin privileges and run the update from that new account. If successful, LR will be updated for all users and you can switch back to your regular user account. If you don’t like the idea of creating a new admin account, you need to uninstall and re-install.
Uninstall using your computer OS e.g. Windows Control Panel or Finder >> Applications on Mac OSX.
Re-boot your computer
Go to the link below and install LR6.0
The download the LR6.5.1 update
Thank you. The uninstall/reinstall worked/end of my frustration.
