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.

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.

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 -

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.

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.

Why And How To Clear Your Lightroom Cache - Lightroom Fanatic

I received an error message in Lightroom 5 , Lightroom encountered an error when reading from its preview cache and needs to quit

I was wondering now that I deleted my preview cache after receiving the lighgtroom encountered an error when reading from its preview cache and needs to quit , light room 5 opened fine now , but I now have no previews showing up , all I get is blank gray boxes ... have I lost everything ?
how do I get the pictures or previews back ...all my folders I had catalogued , now show only grayed boxes where the previews were ... can I get this back ?

I will check for the meta data.. as to hows this adobes fault....first let me ask do you work for or get paid for by adobe? If the answer is no, which i presume it is...then that answers it... how is it , or better yet why is it a billion dollar company, has or offers no support, no phone number, no email nothing...but depend on third party people who may or may not know or give the correct info to help, and do this free, all the while adobe makes $$$ and runs smaller companies that may have actually better products by getting or buying off reviews etc..that only rave, but never mention issues...the issue im having has been reported by adobe users since version 1, yet has not been addressed or even mentioned...why shouldusers get little true support from adobe, get a product that has un addressed issues is messed up...it would be like ford making newer vehicles say a f150, advertising all the bells and whistles , but knowing since their 2008 model that if you go over 70 mph for more than 100 miles the engine will just shut off, then have know way to contact them to solve the problem...had no mechanics to fix it...no warranty...that would be insane...but yet companies like adobe and microsoft do this all the time, but since its notlife threatening as driving a truck would be somehow we accept it as ok....yet it sickens me the hardearned money spent on their products, its an investment, like whether or not to go canon or nikon..your investing in the company its not easy to switch once you make that intial choice... adobe and microsoft continously advertise all the so called (al beit meaningless) upgrades or improvents which are more fluff than worth while improvent, but the way they present them you feel you need them...if they went back to the true ethics of buisness and american pride they would focus moe money and attention to customer service, and truly improving the product rather than how to sell more...but then they know like my camera example once you choose your theirs...sad...i had an adobe salesman out right lie to me and misrepresented a product, as i was having an issue getting sound to work in creating a video of my granddaughters birth...i was using an older version, told him all the info , he said if i upgraded i would have no trouble, so i did...the sound still didnt work . Then they suggested another program to convert the files more money down...the other company also makes video editing programs, once that work...and cost less...but i am all tied up in adobe spending hundreds all ready...sad ...very sad...now that ive had some issues and have gone back and done more researching i see all tge issues, many go back 10 plus years and have yet to be addressed...yet many otherless known third party companies had similar issues, corrected them , are cheaper, have support teams but arent pushed in every photo magazine etc...and arent known where giants like Adobe that dont address there issues have or offer no Adobe paid support, yet through their money and muscle to dominate magazines, and web, by controlling how things are precieved....sad in deed...the more i learn, and experience the sadder things are....but enough complaining sadily im invested in adobe for now till i get rich, just want the crap to work...so i can get my cherished pictures , once in a lifetime pics of my granddaughter back...to bad people have to place faith in a company and risk loosing all the pictures that mean something to them,and realize the comoany only truly cares about $$$...sad

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 probably need to delete your preview cache. See here

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.

"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!
