i have a stand alone version of Lr6 on an iMac. I have tried to install the latest update (July 2016) and got an error message U44M1P28. I followed instructions and tried it again several times, starting again my Mac, etc... but the result was the same. I cannot find any explanation regarding this error. what is the best way to proceed.
was there any additional information on this?
Update is not applicable. Error Code: U44M1P28
You can try to install the update manually by download the update file from here: Download Photoshop Lightroom
If this doesn't I would suggest to deinstall Lightroom and do a fresh installation. You should download the installations files from the link above
