Have Lightroom 6.0 (Camera Raw 9.0) installed on a Mac Pro OS-X 10.9.5. Adobe Application Manager downloads January 2016 Lightroom update. Update process starts then fails with a pop-up box 'UpdateFailed. Updates could not be applied...' The error log, while not very informative, indicates Error Code U44M1P7.
This has occurred several times.
Thoughts? Assistance appreciated.
Good morning and thank you for your assistance. I had to take option 3 - uninstall and reinstall. Then the 2016 update (aka Lightroom 6.4) was successful. Thanks, again!
