I would like to update Lightroom version 6.8 on 6.10. I have the boxed version (so bought, not leased.)

When I click on Update in the LR Help menu it opens the cloud cc app. There it shows next to lightroom: "up-to-date".

I could find an updater dmg at adobe. This starts the installation of the manager app and quits after two percent. with error code u44m2p28.

From Adobe I found several recommendations to solve this issue, none of them worked for me. (log out and in / delete a file in the user library application support). I phoned the support but he told me they would not help with the boxed version of LR.

In the web I find for this update problem only a solution to uninstall LR completely, then to install 6.0 and then install the update. There are these contributions since approximately 2014.

Is it nowadays in 2017 indeed still so that a boxed LR update works only with this strange method?

Or does anyone know an alternative solution meanwhile?

Any hint appreciated,

Thank you!
