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.

I have my catalog on an external hard drive, trying to open it and the error message saying "lightroom encountered an error when reading from its preview cache and needs to quit" how can i fix this as all my work in in this

I have let it close down put it keeps appearing

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.

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

Use Windows Explorer to open the folder containing your catalog. The normal location is Pictures\Lightroom. Locate a folder with the extension .lrdata and delete that folder. Then you should be able to start Lightroom again, and Lightroom will begin building and new previews folder. Do not delete anything else.

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.

Delete the preview cache using your operating system. It is a folder whose name ends with Previews.LRDATA. Do not delete the Lightroom catalog, which ends with .LRCAT

Check this thread. Your Previews Cache files are corrupted.

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

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.

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

I keep receiving this error every time I open LR, "Lightroom encountered and error when reading from its preview cache and needs to quit" and the app won't open. It said LR would try and fix this error next time I opened it but the error remains. I tried uninstalled and installing the app and the error remains.
Any Ideas here? Is there another app that may be telling it where to look for the cache and it no longer there? I was using a ramdisk for a bit but ditched it. Not sure if that has something to do with it but it seems suspect.
Your thoughts?

Talked to Adobe support this morning, this is their response in case anyone else is looking for help. I'm running a Windows 7 box, LR 5.6.
Gokul: Click on start and type %appdata%, then open roaming folder.
Edward: ok
Gokul: Open Adobe folder.
Gokul: Open Lightroom folder.
Gokul: Open Lightroom folder> Preferences.
Edward: ok
Gokul: Rename Lightroom 5 Preferences.agprefs file as Lightroom 5 Preferences.agprefsOLD.
Edward: OK
Gokul: Please check if you can launch Lightroom without any error.
Edward: it shows me a welcome screen and is asking me to select my country
Edward: aka, register the software
Gokul: You can skip and launch it.
Edward: LR catalog not found
Gokul: Please select the catalog.
Edward: my original catalog?
Gokul: Yes.
Edward: testing integrity of catalog
Edward: loaded just fine
Gokul: Okay.
Gokul: Please check if you can re-launch it again.
Edward: yes, it worked!
Gokul: Excellent!
Gokul: Since your preferences were corrupted you were facing issue so we renamed the preferences file to reset it.
Edward: aha....ok
All of my import/export presets were intact along with develop user presets. I'm happy as a clam for my $10/month!

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.

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.

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.
