More then 10 days without working solution...
I downloaded LR CC and I cant start it. Tried sign in/sign out from CC, tried restart, tried uninstall and new install, tried find library file... NOTHING helped.

All what I have is still this:

Error says that problem is in libcef.dll

If you do some google search on "exception code c000001d libcef". You might find reports that the issue might be related to some corrupted Windows system files. And the issue is not unique to Lightroom.


Has a reported solution. Some user there reported reinstallation of Windows helps.

Installation of SP1 to Win7 helped me.
