Lightroom CC won't open

I just wanted to say the thanks to the community I was able to fix this by doing repair for Visual C++ Redistributable for Visual Studio 2012 Update 4.

I am concerned that Adobe have had no input or offered help with in this thread and Adobe support is basically non existent. We are all paying top $ for this average app with no support! Adobe would have to be one of the worse programmed programs in the history of computing!

MS Office offers a massive program suite and it cost is about $99 a year and yet Adobe want $600 a year for its mess!

This is so annoying, This is really adding more stress to my day and I am on a deadline. How can i get LR to work on my mac? I have tried signing out then back in many times and yet it still does not open. This is doing my head in... I expect better from Adobe. Any advice will be greatly appreciated.

that's hardly a fix .. especially if it doesn't work .. well it doesn't work for me

So LR had stopped opening for me as well since my latest Mac update 10.10.5. I have read through the above, the Visual C++ is only for windows, any suggestions for a Mac??

If I force quit it is visible in there but when I force quit and open it again it just bounces up and down and nothing more

I have also got problems

Windows 10, sign out and in is not working, reinstalling several times, not working, cleared adobe OOBE and AAMUpdater and reinstall of creative cloud.

Nothing works

It's indeed silly but signing out / in again solves it for me.

I've had Creative Cloud for a few months. I bought Lightroom CC and Photoshop CC and they worked fine until quite recently. I wasn't able to open either of them. I kept getting an error code when I opened Photoshop but it has now been resolved and now I can reopen it (although it took me several hours to find a way to fix it and now it says there are display problems so, even though it works, the display is quite different.) However, I just can't open Lightroom at all. It doesn't open and then immediately close, nor does it give me an error message. It just simply does not open at all. The loading icon appears next to my mouse but only for a second or two and that's it. I've tried uninstalling/reinstalling everything to do with Adobe. I tried signing in and out of CC in the top right corner under preferences and I still can't get it to open. Can somebody help me please?

I am having same issue but didn't happen till Windows 10 "upgrade".  Photoshop opens just fine.  Lightroom is like I never clicked the button.  Signed out and back into CC twice to no avail.

Signing out and back in is not helping. It just won't start no matter what I do. I have customers waiting on me!

‌After  tearing my hair out for a day over this, including several removals and reinstalls of the entire CC system, including removing every reference I could find in the windows registry before reinstalling, the only way I could get things working was to restore a Macrium backup of my entire Windows system from early November. A regular Windows pre-upgrade restore failed to get Lightroom working. Now I suppose we can all life in fear of Windows 10 upgrades because CC will be crippled. The strange thing, as many of discovered, is that when it was broken LR wasn't even attempting to start. There was no trace of anything in Windows processes.  It was as if  Lightroom ceased  to exist. Even starting directly from the .exe file would not work. in my case, the strange blinking screen in Photoshop was also very odd. It wasn't the entire monitor that was blinking, only the area within Photoshop – – white to black and back about three times a second. It would only stop if I open a photo for the editing. What a mess!
