I have the upgrade LR5. I have no choice for a default editor; all are grayed out and there is no drop-down choice box. I can only use CS6 as an alternate editor. What do I do to get CS6 as my default editor?
I am having a similar problem. LR5 does not recognize that CS5 is the latest Photoshop version installed. CS3 is listed as the default editor. CS5 works perfectly as an alternate editor. LR4.4 has always shown CS5 as the default editor.
The problem was solved by defining the path to CS6 in the registry. See kb4011629 for details, or Go to http://helpx.adobe.com/x-productkb/multi/edit-photoshop-command-missin g-photoshop.html
