Hi Canis dirus arctos,
What if you try renaming both the SLCache and SLStore folders prior to launching Lightroom?
Locations of both of these folders are located in Solution 3 of this document: https://helpx.adobe.com/lightroom/kb/unable-launch-lightroom-55.html
If you'd like to change permissions first as a test, then renaming the folders and report back the findings of both methods, that'd be great!
Let us know how it goes.
many thanks, will try that after work and give a feedback afterwards. Kepp my fingers crossed
I tried it an things even get more worse.
Changing permissions didn't help at all.
Changing the folder names caused, that even after new cloud login I had to active Lightroom in an endless loop. After reactivating it has been set to test subscription, after new login the same again.
My only chance to get at least the rest of CC running has been, to logout from the desktop app, renaming the opm.db, starting Photoshop and do a login from there.
Lightroom CC still doesn't work. I can start it and even generating a new catalog will let LR freeze within seconds.
Just got confirmed, that my problem seems not to be related to the known login/authentication problems, so all the solutions allready provided will not help.
My problem occurs after successfully passing the LR startup and authentication part while or after opening a catalog. (cannot say exactly)
All I can see is, that a new catalog can be generated (and an older be opened), folders and files were written and then it freezes. On the WIN 8 machine this takes a few seconds without causing problems, on win7 64 it stucks in this part.
So, permissions seems to be fine, authentications is no issue and unfortunately the system logs only show a not responding process.
Also doesn't make any difference if I start it as admin and disable protection tools (which are not blocking on the win 8 anyway).
Funny is, that LRCC runs on my AMD-C50 based convertible, but not on the performance machine under Win7 64.
Anyone an idea if there might be a problem regarding specific graphic cards or drivers or what might cause such effects? All the other CC apps are running fine.
cheerz and many thanks
I finally fixed my issue by creating a new useraccount (and now I have to do some for sync the old user data), but on the new user account its works fine so far.
Seems, that a few persons had similar problems and have been able to get rid of it by creating new user accounts.
But I should not ask myself why only Lightroom CC has any problem with the old account, that's less funny anyway
