Lightroom encountered an error when reading from its preview cache and needs to quit. Says Lightromm will attempt to fix the problem the next time it launches, but on every re-launch I get the same message. Any clue as to how to fix this problem?

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.

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.

"Lightroom encountered an error when reading from its preview cache and needs to quit. Lightroom will attempt to fix this problem the next time it lauches". What do I do? I get the msg each time I try to open it.

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.

Re: "Lightroom encountered and error when reading from its preview cache and needs to quit"

When backing up lightroom 4 catalog, get message "lightroom encountered an error when reading from its preview cache and needs to quit" this occurs during optimization stage of backup

i upgraded from lightroom 4 to lightroom 5 and installed it on a separate hard drive. Initially had no problems util my computer crashed due to the failure of the drive on which Lightroom 5 was installed. Since having my computer rectified, i am unable to use lightroom 5 getting the message "lightroom encountered an error when reading from its preview cache and needs to quit"
I can still use lightroom 4, however, i get the same message when i try to backup the catalog. This occurs during the optimisation phase of backup.
I suspect it is related to Lightroom 5 creating a catalog from the Lightroom 4 files and cannot now locate those files or that they have been corrupted.
Would appreciate any solutions / suggestions.

You need to delete your preview cache and have Lightroom rebuild it. Cache location can be found here.

I get the following window on loading Lightroom 5.7 -
Lightroom encountered an error when reading from its preview cache and needs to quit.
Lightroom will attempt to fix this problem next time it launches.
I have tried several restarts, without success. Also reinstalled Lightroom; no joy
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.

Open the folder containing your catalog. In that folder you will find another folder with the extension .lrdata, and you need to delete that folder. After you do that, Lightroom should start normally and will create a new preview cache.

LRCC Error: Lightroom encountered an error when reading from its preview cache and needs to quit.

I just upgraded from LR 5.7.1 to LRCC a couple of days ago. After working with a collection of images in Lightroom CC, this message popped up: "Lightroom encountered an error when reading from its preview cache and needs to quit." What do I need to do to remedy this? Thanks!

Quit Lightroom
Then 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.
Re-launch Lightroom after deleting the Previews folder.
N.B. do not touch files ending .lrcat

Ightroom 5.7 "lightroom encountered an error when reading from its preview cache and needs to quit"

I got this error message after start in Lightroom 5.7 "lightroom encountered an error when reading from its preview cache and needs to quit". It seems also catalog .lrcat disappears from disk. Also preview catalog .lrdata doesn't exists. So I try to reinstall Lightroom without success, I am still receiving the same error. How I can reset Lightroom to new catalog? I have backup of lrcat file, but I am not able to start Lightroom due to this error.

It seems solved. I have copied backup .lrcat to Lightroom data directory and I still have received error mentioned above. But when I doubleclick on .lrcat file in Explorer the catalog have been opened without problems.

I assume you know where your catalogue file (the lrcat file) is located. In the same folder is a previews lrdata folder which you should delete or rename in Explorer, then start LR again.
If I've made incorrect assumptions above, sorry, and we'll go back over it from the start.

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?

Can some one please help me with this error message I keep getting. I was told to uninstall LR and reinstall it and I am still getting the same error message. "light room encountered an error when reading from its preview cache and needs to quit"..

Go to the folder containing your catalog, and delete the folder that ends in .lrdata. Then start Lightroom, and it will create a new preview file, and you should be good to go.
