"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!

Error Launching LR 5: "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 launches."
I've tried renaming my catalog.lrcat file. I've copied over my most recent backup of the catalog.lrcat and that didn't work either.On Mac:
PS - to open the previews "folder" (a "package" is just a "special" folder) on Mac, ctrl-click and choose "Show package contents.." - same way you open any other special folder, like .app or .lrplugin..

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.

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.

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.

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.

Every time I open lightroom I get a pop up message saying "Lightroom encountered an error when reading from its preview cache and needs to quit" and it closes. Ive already tried reinstalling, nothing seems to work. Help please!
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.

Lightroom 4.4 keeps crashing saying "Lightroom encountered an error when reading from its preview cache and needs to quit" please help. I've tried reinstalling it and everything Windows 8.1
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" 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?
