I am having problems with my publishing services. None of them work unless I run CC in Administrator privileged mode on Windows 10.
If I do not launch with Admin privilege then a get multitude of errors about not being able to create temp files whenever I try to publish something.
I did not have this problem on v6 but now that I am v7 this has crept in.
So far I have removed and re-added the plug-ins, and re-installed LR.
There do not appear to be any other issues with LR other than this from what I can tell.
We're really sorry for all the trouble caused you. You may try enable the hidden admin account on your Windows platform and try using Lightroom there.
Please refer the following link to enable the hidden admin account: How To Enable Hidden Administrator Account In Windows 10
Let us know if that helps.
