Hi,
Until I upgraded to Windows 10 Creators, I had to run both Photoshop and Lightroom in administrator mode, otherwise I always got the infamous error 16. I never could fix that. After the upgrade, both programs appeared to behave normally, although I had unchecked the "Run as an administrator" option in the Properties of each .exe file.
Then, in Lightroom, I tried to "Edit in..." Photoshop from Lightroom. And PS emitted the error 16 again. But if I launch PS or LR directly, there's no error.
Now to the fun part : If I want to get rid of this error message, I need to set the "Run as an administrator" option for either Photoshop OR Lightroom. Not necessarily for both. Once one of these programs has its "Run as an administrator" option checked, there's no longer any problem.
Now if someone from the development staff could explain this oddity, I would appreciate (you can get technical, I'm a former developer and system engineer). I have multiple times checked all the permissions that are described in the various documents explaining how to fix this annoying and boring "configuration error - error 16" bug. To no avail.
I'm running Windows 10 Creators, PS and LR CC latest version. My TMP and TEMP variables point to a non system drive.
I have monitored the photoshop.exe process and I observed a problem when photoshop.exe tries to access C:\Program Files (x86)\Common Files\Adobe\SLCache\QUNDRVNTX0NIRUNL.slc in read/write mode. Just before this event, I can see that the file is accessed in read mode multiple times without any problem. See log file here (look for "access denied") :

I have checked the permissions for this folder and for the file itself : all users including Everyone have full control for this folder and for this file.
