I have a LR 6 (box version) Licence that allow me to install LR6 on 2 computers (macbook and my mac).
yesterday, I apply Apple Security Update on my mac and now, LR6 tells me that I can't use my licence anymore on my mac,
it lets me 30 days as trial (29 this morning).
What can I do ?
That security update might of changed the permissions on the folder that the license info is stored in and now won't allow Write access.
Look here for details.
Also make sure you are signed in properly. IE using the correct Adobe ID.
You may also have to re-enter the serial number for LR.
I have verified the permissions and it seems to be correct.
On my mac, when I launch LR6, since I applied the Apple Security Update, Adobe Application Manager tells me that all my licences are already used and I need to enter a new licence number.
