Rename or delete the lrdata file. Then start Lightroom and it will create a new one, and will begin generating new previews.

Error message on start up "Lightroom encountered an error when reading from its preview cache and needs to quit"

Error message on start up "Lightroom encountered an error when reading from its preview cache and needs to quit" I uninstalled and downloaded it again and still get the same error. At this rate I won't have any chance to use the 30 day trial period as it simply isn't working. I have see suggestions elsewhere to delete a particular file, but I don't have it. Any ideas?

You need to trash the preview cache. It’s in the main catalog folder.
Delete the folder with the ending Previews.lrdata
The default location for the Lightroom folder is normally Pictures/My Pictures if you did a standard installation.
N.B. do not touch files ending .lrcat

You don't delete a file, you have to delete a folder. Is that what you did?
If you deleted the folder specified above, and you still get the message, then it's the wrong folder. Use your operating system's search function and find ALL folders on ALL disks whose name ends with Previews.LRDATA, delete each one found, and then try opening Lightroom.

It isn't a file, it's a folder. It will have the same name as your catalog, but will have the extension data. It will be in the same folder along with your catalog. If you need to use the search feature to search for *.lrdata.

I get the following window on loading Lightroom 5.7 -

Any suggestions?

Using your system browser (Windows Explorer or Finder), open the folder that contains your catalog. In Windows it is in your pictures folder and then in a Lightroom folder. Inside of the Lightroom folder you will find another folder that has the extension .lrdata. It will have the same name as your catalog except for the extension. You need to delete that folder, and then start Lightroom again. Lightroom will generate a new previews folder, and you should be back in business.

Hi All
My computer crashed with lightroom open, since restart I get a msg 'LR encounted an error when reading from its preview cache and needs to quit'
I'd appreciate any suggestions
Many thanks

Many thanks for your help, at lease the LR is working now. How do I rebuild previews and smart previews or will this happen automatically?
Many thanks

I recently updated my HP laptop's OS from WIndows8 to WIndows8.1. When I went attempted to open Lightroom5 I got the following message:
"Lightroom encountered an error when reading from its preview cache and needs to quit. "
"Lightroom will attempt to fix the problem the next time it launches"
Every time I relaunch I get the same message. I'd like to understand what might be causing the problem so I can remedy and get back to my photo editing. Any clue as to how to fix this problem would be greatly appreciated.

When I try to open my Lightroom 5 program it comes up with this message, "Lightroom encountered an error when reading from its preview cache and needs to quit." How do I fix this?

Can someone please let me know how I can fix this error and open my Lightroom? Thanks.

You might be quicker help posting in the LR forum rather than the ACR forum, but I believe the way to fix this is to delete the preview cache.
Find your catalog folder.
Close LR.
Within the catalog folder, delete the FOLDER called Catalog-Name Previews.lrdata
Start LR.

You do not want to delete your catalog file Lightroom 5 Catalog.lrcat with extension .lrcat. This will cause you to lose all of your image editing information.
Locate and rename the Previews Cache folder named Lightroom 5 Catalog Previews.lrdata by adding a .old to the extension (Lightroom 5 Catalog Previews.lrdata.OLD). Restore the original catalog file from the Recycle or Trash bin if possible. See procedure here:

I have the following problem: Lightroom encountered an error when reading from its preview cache and needs to quit. Lightroom will attempts to fix the problem the next time it launches.

I launch and relaunch and the same message appears over and over.
Should I uninstall and then re-install Lightroom? Would this fix the problem?

Thanks Jim.
I will give it a try.
My "Lightroom 5 Catalog Previews.lrdata" folder is 12.3 GB in size, so the rebuild will take lots of time...right?
I'll let you know how it goes.
Ciao.
