Please set Lightroom to open as an Administrator and see if that makes a difference
- Close Lightroom(make sure it is not open in task manager)
- Navigate to C:\Program Files\Adobe\Adobe Lightroom Lightroom.exe
- Right Click Properties>>Select Compatibility
- check "Run this Program as Administrator"
- Click Apply and then Ok.
- Close Lightroom(make sure it is not open in task manager)
Makes no difference. I get the User Account Control dialog box each time I launch Lr. But Lr fails to launch after quitting the 1st time.
Lr appears to close fine. I get the dialog box to backup the catalog and I have tried both backing up and skipping, but the results are the same.
Tried unchecking the "use graphics processor", no change.
Found something odd.
Our previous troubleshooting step was to disable the graphics processor by unchecking the box. I did that and found my original problem still persists.
So, I went back in to re-enable the graphics processor, but the box was already check. Seems that by killing the Lr task in Task Manager causes my preference change not stick.
Please reset Lightroom Preferences
Backup your catalog and close Lightroom
Press and hold CTRL+ALT+SHIFT while starting Lightroom and select yes on the Prompt to reset Preferences.
If that does not work
Could you do a test to check whether Lightroom performs similarly in a new Administrator account
See How to Create a New Local User Account in Windows 10 and use Lightroom in new user account
Let us know the outcome
Since I already had a dummy standard user account setup I went ahead and tried it. And I was able to successfully start-shutdown-restart Lr with no apparent issues. To be clear, this was a standard account that was never used.
I haven't tried resetting the Lr preferences yet. Do we need to go down that road? I don't remember exactly what changes I have made in the preferences panel to customize Lr to my liking. But I will reset it if necessary.
If it works fine in the new account that means the issue is with the standard account as it does not have Full Permissions .

Yes it will be a good try anyways
If it doesn't work .Would recommend you to use the new account.
But wait,The account that I normally use is the administrator account and that is when Lr fails.My unused account is a standard acct. and Lr succeeds.This doesn't make sense to me.

It could be visa versa .Basically issues are with the user account
Did you tried preferences reset?
"Press and hold CTRL+ALT+SHIFT while starting Lightroom and select yes on the Prompt to reset Preferences."
This does nothing on my Win 10 computer.
Does this work in Win 10?
From the Adobe site......
Reset your preferences
To reset your preferences, do the following:
- Quit Lightroom.
- Navigate to the preferences file:
- Mac OS: /Users/[user name]/Library/Preferences/com.adobe.Lightroom5.plist
- Windows 7, 8: C:\Users\[user name]\AppData\Roaming\Adobe\Lightroom\Preferences\Lightroom 5 Preferences.agprefs
- Drag the preferences file to the Recycle Bin (Windows) or Trash (Mac OS).
Normally it should work See Resetting Preferences in Lightroom CC/6 | Lightroom Blog
You need to hold down the keys before you open Lightroom and keep holding them until you see a prompt to Reset preferences
Sometimes you may get a prompt from UAC.to allow Lightroom to make changes.Select yes but keep holding the three keys to reset Preferences
Your link describes the process differently:
"How do you access the dialog? Well you need to restart Lightroom, and then hold down the Shift and Option keys on Mac, or the Shift and Alt Keys on PC. The Reset Preferences dialog appears."
I did that but it didn't help.
That puts me back at administrator vs standard account. So, I don't understand why Lr had been working fine under my normal acct., for some time then Adobe does a patch, now its broke.
You are telling me that I should use my other account even though all My Documents, Music, Pictures and Videos are NOT associated with that account. I see a real mess ahead of me trying to switch everything over.
Surely there must be another way!
I haven't tried resetting the Lr preferences yet. Do we need to go down that road?
Yes. Many people have reported this bug, and for many of them, resetting the preferences fixed the problem. See this bug report in the official Adobe feedback forum: Lightroom 2015.2:Hangs on quit. Please add your vote and details about your issue to that bug report, to help Adobe understand the scope of the problem.
Bingo! I finally got the right combination of keypresses and clicks. On my computer if I press and hold the shift and alt keys while clicking on Lr desktop icon, then release everything, nothing happens. However, if I click the desktop Lr icon then quickly press shift-alt I get the dialog box to reset Lr preferences. I did that and now Lr starts and stops , as expected.
I'll post my results on the page that John referred me to.
Thanks to all for your help.
This is ridiculous. Lr is back to not closing completely again. I'm not inclined to go through the preferences reset again. I hope Adobe is working diligently on the fix.
Adobe has apologized for the mess created with LR CC 2015.2 and 2015.2.1: http://blogs.adobe.com/lightroomjournal/2015/10/lightroom-6-2-release-update-and-apology.h tml, Lightroom 6.2 Import Update. But it could take them a while to dig out. Meanwhile, many, many people have reverted back to CC 2015.1.1 / 6.1.1, the last stable release: How do I roll back to Lightroom 2015.1.1 or Lightroom 6.1.1?. It's easy and you won't lose your settings or changes to your catalog. Wait until there's a new release and let others do the beta testing.
