Yes:
Step 1: Delete the preview cache.
That's it!
So, the trick is to find the preview cache.
This document gives location:
http://helpx.adobe.com/lightroom/kb/preference-file-locations-lightroom-41.html
To be clear: it's a folder in with your catalog and you want to delete the whole folder but nothing else.
If your catalog file path is "X:\My Catalogs\My Catalog.lrcat", then the preview cache "folder" will be:
X:\My Catalogs\My Catalog Previews.lrdata
So the trick is to find your catalog file, and since Lr won't open your catalog and run, you can't use it to find out.
But you should be able to find it by searching your disks for *.lrcat files - do you know how to do that?
Which OS?
If you know the name of the catalog it will help, but also: it's probably NOT in with your program files.
UPDATE: The above-mentioned document gives default name and location for preview cache, so if you haven't overridden the default, it should be right where that document said it would be - is it? (of course you need to know your user name too, but presumably you do, no?).

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. I have windows 8. Can anyone please help???
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.

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

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.

Upgraded to 5.4 when opening lightroom get a message "encountered an error when reading from its preview cache and need to quite" tried this several time but get the same error message. Says Lightroom will attempt to fix the problem the next time it launches but that is not happening. How do it fix this?
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

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. -

See if the issue in the thread above helps you to solve your problem. -
"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.

"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?
--Kenny Brandon WilsonTalked 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.

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! -
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.
