I am getting this message when trying to open Lightroom 4. I have had no problems ever before. Any solutions?
I have finnaly solved this, and maybe it will work for you too. Run Lightroom as Administrator, that did the trick!!! YES!!!
Thanks

I had the same problem on Windows 10. I was able to solve the issue by running Lightroom as an administrator and my catalog opened.

This is a really old question, but I faced a similar issue today and here's the process I went through:
So if you encounter this issue, checking the attributes is a good idea.

I've tried changing the attributes, but it hasn't helped the problem. I changed attributes on the Lightroom folder and on the Pictures folder. Is that what you did?

No, I changed the attributes on the catalog folder. On my system, the images are in a directory on the D drive and the catalog is on the E drive. Find your catalog file and check that. I think Adobe defaults to placing that in the Pictures directory, which is under your account directory on the C drive.
Note that I also uninstalled and reinstalled Lightroom CC at the same time. It's a bad practice to make 2 changes simultaneously, but that's what I did. One change or the other fixed the problem, so if changing the catalog directory's attributes doesn't do it, uninstall/reinstall might work. MOST (but not all) of my settings were preserved.

I had a similar issue and was getting the same error message on my main catalog and all my backups. I went in and changed permissions on the catalog file and then had to RESTART my computer for it to work.
I just had to have my operating system reinstalled as well (and had to reinstall ALL of my applications!!!) so guessing that the permissions issue had to due with that. When I got my computer back from Simply Mac my user password also wasn't working so I had to go into recovery mode and reset so it makes sense that it was a permissions issue. The weird part was that I reinstalled Lightroom and was working from my catalog fine and then it quit on me due to an "unexpected error" and then I was getting the same unexpected error trying to reopen the catalog and all of my backups.
THANK you to everyone who has chimed in here with helpful hints and things to try. SO, SO, APPRECIATED!!!

Got this error message on one of my catalogs, all other catalogs were working fine. I think it was caused by removing hard drive while the catalog was open.
FIX:
Will take a long time if you have an enormous catalog!

Had the same issue today (for the first time). I had my back-up programme backing up LR at the time so paused the back-up and then LR opened normally. Hope that helps.

I have the same problem - "Unexpected error opening catalog". I don't have any problems with the hard drive. The system (Windows 7) is in small SSD C:, all data is in disk D:. One day Lightroom stopped opening the catalog, and that's all! My clients are waiting for the result, and I cannot answer them "My Lightroom is broken", Disgusting situation. And no any decisions by Adobe

This one saved me:
Windows Defender Security Center
Virus & threat protection
Virus & threat protection settings
Controlled folder access: TURN OFF

last post helped me with the same problem after I locked down some settings a few months back with Windows Defender. Rather than turning off virus and threat protection, I enabled Lightroom to get through instead.
Once I did that, I was finally able to successfully open Lightroom once again. What is a real shame is that Windows Defender allows us to lock down our computers (which is fantastic), but doesn't provide proper errors when programs encounter errors because of this lockdown. That's really unfortunate because I've encountered similar errors with other programs. It can be really frustrating because I really want my computer to go back to how it used to be without these problems (especially as more time passes since I set up Defender to better protect my computer from intrusions), however I know it is better to have it setup this way. Just wish Defender provided better errors when programs encountered the new rule I setup with Windows Defender.
Hope this helps someone else after I messed around with all of this for the past half hour just so I could edit 20 photos completely unrelated to any library from earlier this year!

YES! THIS WORKED! I have tried literally everything else. The weird thing is that controlled folder access was set to OFF already, but then when I turned it ON and allowed LR through as described above, the catalogue opened. Hope this helps someone!

Running the app as admin may not solve the problem for everyone. I found a solution in my case. If you wish, read ahead to know my situation and how I diagnosed it or just skip to the highlighted solution part.
I installed LR and on the first attempt (while my internet was down and windows defender was disabled) it opened the catalog without any issues. Then I had work on the internet so I turned on both my antivirus and my internet and after that Lightroom crashed saying it ran into some problem and needed to close. When I reopened, it would not open my catalog. I could create a new one and it would work fine but my original catalog had over 4 years of work in it. I just couldn't give up. So I noticed what triggered the event. 2 possibilities. 1. Catalog got corrupt. 2. Windows Defender. Since I had made over 43 backups of my catalog in various different places included 4-5 cloud storages, I tried about 7 of them and all of them failed to open. So the only issue left was Windows Defender. I tried to turn everything off in Windows Defender and reopen my LR but it didn't work. Finally I recalled same thing happening with FIFA19. It would just crash on opening. So I applied the same solution I used in FIFA19 over here.
Solution:
Go to Settings app > Update and Security > Windows Security > Virus and Threat Protection > under virus and threat protection settings click on manage settings > scroll down and you will see 'controlled folder access'. Click on 'manage controlled folder access' under it > allow an app through controlled folder access > click on add an allowed app. Browse to Lightroom Installation folder (Generally: C:/Program Files/Adobe/Adobe Lightroom (or just Lightroom)). Now close any open apps and launch lightroom. It should read your catalog fine. Lemme know if this method helps. This is an annoying little feature from windows that blocks access to certain folders for all apps for security's sake.
