Is the system on Domain ?
What is the OS ?
Is Lightroom up to date ?
The system is Windows 7 Professional.
I have Lightroom 5.7 on the same system that works regularly.
The version of Lightroom is 6.0.
This solution don't work.
I have the same problem.
Thank you very much!!!
I have reinstalled Lightroom 6 and before doing anything else I upgraded to version 6.3.
Now it seems to work fine.
Why Adobe does not directly download the full latest version updated?
