Unexpected Error Opening Catalog

[brhull]

I merged my LR catalogs and lost my develop edit history. I deleted my previous catalogs but have now recovered them. However when I try to open the old catalog files I get the message 'unexpected error opening catalog'. How do I recover my old catalog and restore my edit history?

Hi Sahil or an other expert!

I have Windows 10 Fall Creator update.  Updated about 10.nov.2017. After updateing my Lightroom (6.12) stopped to work. I can´t open my Lightroom. If I try I get this information:

I have used button "Choose a Different Catalog" After this I get a new box:

So, "Choose a Different Catalog". Where is it ? I didn`t find different catalog. I just finded Lightroom Catalog.lrcat  and it doesn`t work.

Next I tried: Create a New Catalog"-button. Thank you, but how does it work? What am I force to do?

I have tried advices as down mentioned.

Solutions

Solution 1: Install the Microsoft Visual C++ Redistributable 2012

• For instructions, see: Error in MSVCR110.dll opening apps in Windows 10

• Right-click on the Lightroom.exe file.

• Choose Run as administrator.

• Right-click on that folder.
• Choose Properties > Security > Edit.
• Select your user name in the Group or user names section. and click Full Control under Permissions.
• Click Apply, then click OK out of all the dialog boxes.

Thanks for solutions, but these don`t work.

I realy need advices but simple and easy, please. (I am not an engineer)

Thank you for sharing the information with us, please let us know did you "Upgrade" the catalog after you updated to Lightroom 6.12?

Hi Sahil!

Thank you for question!

First I upgraded Lightroom (upgraded 17.7.2017) and after this Windows 10 (about 10.11.2017).

Thanks for the info, could you please open Lightroom then go to Help > System info and share it with us?

Hi Sahil!

The main problem is that I can`t open Lightroom, because difficulties to open lrcat.

Hi Sahil, again!

I don`t know what to do with "Chooce a Different Catalog" or "Create a New Catalog"? How can I find (or Chooce) a New Catalog or how can I Create new Catalog?

Once you click on Create a new Catalog, you'll be prompted to give a name for the new catalog and Lightroom will open up with the new catalog. And the default location of your New catalog is C:\Users\Username\Pictures\Lightroom

Thanks Sahil!

I tried to get a new catalog as you told me to do, but I wasn`t succeed. I tried different names for ex.

Lightroom Catalog 2.lrcat.

So, what should I do next?

As you can see there isn`t any new catalog. Only the old one, which doesn`t work.

Have a nice day.

Try giving the new catalog a name such as 'Test'
