Lightroom does not open..  I uninstalled then reinstalled LR CC to no avail; I signed out of Creative Cloud I signed back in... NOTHING... NADA!!

Please reboot the computer .

After rebooting , sign out from Creative Cloud and Sign in .

Then try to launch Lightroom cc 2015 .

Let me know if you still face same issue.

[smekata]

Same thing here.

Didn't make any difference here. Mac OS 10.10.3, LR CC.

[Govardhan.V]

Okay, Please follow below steps:

1) Right click on Finder icon and  select "Go-To" Folder option.
  2) You will get a text box, type-in below command and then hit 'Return' key.( Do not miss ~ symbol)

~/library

Under Library  , locate Preferences folder and open the same.

Then look for plist file for Lightroom application and move it to Desktop .

Make sure there is no Lightroom com.adobe plist present inside .

Then sign out from Creative Cloud and sign in and try to launch Lightroom application.

[Govardhan.V]

Look for file named com.adobe.Lightroom6.plist  under Preferences folder and move it to Desktop.

[smekata]

Thanks, but getting rid of com.adobe.Lightroom6.plist didn't help, either. Tried variants like signing out, deleting prefs, rebooting, signing back in...same thing.

I noticed that shift-option when launching LR CC also asks if you want to trash the prefs - I think that does pretty much the same thing and that didn't help, either.

‌I have encountered the same issue.

[Govardhan.V]

Please try with above steps and check once again.

[drose49]

‌it correctEd the issue for me.  Thanks

[Govardhan.V]

Perfect!
You are most welcome

Right click on the Preferences folder under ~/library  and select GetInfo option.

Expand the Sharing & Permissions section.

Click the lock icon in the lower-right corner. Enter your administrator user name and password when prompted, and then click OK.

Please click on '+' symbol , it will open list of user accounts.

Add all user accounts and then provide "Read & Write" permission to all user accounts.

Click the Gear icon, and select Apply to Enclosed Item. Close the Get Info dialog box.

Once you had provided read and write access to all users like Currently logged in user , Administrators, Staff...etc . reboot the computer again .

Sign out and Sign in to Creative Cloud and try to launch  Lightrom cc again.

[smekata]

No, no one should be required to make their preferences folder wide open to all users to get LR CC to work. I'm not going to try that.

[smekata]

[But thanks for your help so far]

[Govardhan.V]

Okay, Provide read & write , to currently logged in user account and Administrator only and check.

[smekata]

Current user and admin set to Read/Write, applied to enclosed items, rebooted, logged out and signed back into CC, same issue when launching LR CC. Splash screen flashes briefly and goes away.

[Govardhan.V]

Smekata,

Please make sure all the preferences file for Lighroom are removed from Preferences .

Then Sign out from Creative Cloud and Sign in.

Note : Do not try to launch Lightroom application from Appplications folder.

Important :

"Launch Ligthroom CC 2015 application , by double clicking on Lightroom cc 2015 option under Apps list in Creative Cloud application"  .

[smekata]

Thanks, but this did not resolve the issue, either.

FWIW, I can see various reports on other threads here and in other forums at other sites where logging out of CC, logging back in, and then opening via the App list in CC app doesn't help (although it does for seemingly the majority).

[Govardhan.V]

It is getting resolved for other , hmm pretty mysterious issue :

Lightroom CC (2015) not updating LR5

[Govardhan.V]

I know it is headache to go through same process again.

Open Preferences folder and move all Lightroom prefernces file to Desktop.

Make sure that not even single Light room  prference files like com.adobe.lightoom.plist...etcare there inside Preferences folder.

Then reboot the computer and Sign out from Creative Cloud and Sign in and then try to Launch Ligthroom CC 2015 application , by double clicking on Lightroom cc 2015 option under Apps list in Creative Cloud application"  .

Still same issue ??

Remove Lightroom cc application and the reinstall the same from Creative Cloud.

Then try launching Lightroom cc 2015 from Apps list in CC app.

Still same issue?

If it is okay for you , you may try launching from Root user account.

[smekata]

FWIW, I uninstalled CC, and used the CC Cleaner tool (Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6) to clean up everything it showed, when through and wiped a bunch of additional preference files and /Library/Application Support/Adobe stuff, reinstalled CC and LR CC, and it works again. I inadvertently also wiped my LR5 library that I had just created from an Aperture library import...so I guess it's back to another day of redoing that! oops.

So no idea what item fixed it, but it was something of the above.
