The other solution to things reverting to trial when licensed is Adobe is telling people to install a specific version of the AAM, so you could try that:
You might also use the CC Cleaner to start over:
Okay. I have tried both of these methods.
The troubleshooting instructions for CC applications ended with the same result as before. I go through the whole process, but when I license my software, close the application, and restart it, I still get the LR CC splash page and AAM saying I have 29 days remaining on my trial.
The CC cleaner didn't work. I don't have any ACC software on my computer.
Does it work any better if you right-click and run LR as administrator?
Does it work to create a new profile on the computer, make it an Administrator, and install/license LR 6, there?
Does it work to create a new AdobeID and license LR 6 with it?
