If Store app not opening in Windows 10 and running App troubleshooter reports unresolved "Windows Store cache may be damaged" message, fix it manually here.

Whenever there happens any issue with Windows Store, users are often suggested to run Windows Store Apps troubleshooter. This built-in troubleshooter helps you to identify the problem with Store and fix it automatically. But sometimes, automatic fixing using this tool may not work, yet you got to know what the issue is so that you can solve it manually.

This post talks about one such issue which is not fixable by Windows Store Apps troubleshooter and it is labelled as “Windows Store cache may be damaged“. We recently came around this problem on a Windows 10 Pro running system for which Store app wasn’t opening and it got stuck at splash screen. Running the troubleshooter found this problem and it seems that we need to fix it manually, as it is quite clear from below screenshot.

2. In LocalState folder, if you find Cache folder, rename it Cache.old. Now create new folder and name it Cache. If Cache folder doesn’t exists by default, simply create the empty new folder and name it Cache.

  • Amazing solution! fix 2 has solved my problem. Many thanks!!!

  • Kapil Arya

    ^^ Glad we could help 😎

  • Still didn’t work for me….I’ve tried EVERYTHING!!! Did everything you suggested, ran the trouble shooter and it’s still says not fixed.

  • Kapil Arya

    ^^ Try to create new user and see if the issue persists on that.

  • My surface pro does not have this location Packages\Microsoft.WindowsStore_8wekyb3d8bbwe\LocalState

  • where can I find my system root drive?

  • Kapil Arya

    ^^ Press Windows Key + E, under ‘This PC’, the drive having Windows logo on its icon is system root drive.

  • Ive spent ages on this issue. Last fix, fixed it! Thank you sooo much.

  • Kapil Arya

    ^^ Happy to help 😎

  • i don’t even have “Microsoft.WindowsStore_8wekyb3d8bbwe” folder in “C:\Users\\AppData\Local\Packages\Microsoft’…….of course i have changed user name to mine

  • Kapil Arya

    ^^ Please confirm, if Windows is installed on C: drive and hidden items are visible and recheck. If Windows is installed on any other drive, check accordingly. The folder must be there.

  • Done all that and it still doesn’t work. The problem is not fixed and when the Store app tries to open I get the message “You’ll need a new app to open this ms-windows-store”. This is the same message I get when I login to my Windows account and try to download any app. I had 4 different tech support people on Chat yesterday and none of them could solve this.

  • Kapil Arya

    ^^ For that error, check following fix: https://www.kapilarya.com/youll-need-new-app-open-this-ms-windows-store-windows-10

  • i opened this folderC:\Users\\AppData\Local\Packages\Microsoft.WindowsStore_8wekyb3d8bbwe\LocalState
    the folder was empty….and if create a new folder cache in it….it vanishes after some time..
    so what to do now?

  • i also tried the fix 1… but it gives ms-windows-store: purgecaches
    invalid values for registry
    error

  • Kapil Arya

    ^^ Suggest you to try creating new user account and see if it helps you.

  • 3/4/17 Tried fix #2 and it worked. I thank you very much. However, Microsoft knows this is a problem and they are selling Windows 10; they should have had an automatic link to fix. I think it’s a shame that it took me over 2 hours of searching to find a fix I could trust. Microsoft should do better.

  • Kapil Arya

    ^^ Thanks for your feedback!

  • i attempted both suggestions, still getting same error message when running the troubleshooter “windows store cache may be damaged”.

    i can open the store but unable to download anything. keep getting same error when downloading that the error is on their end, worked ok earlier today, then tried to download something later but failed.

    run troubleshooter just to see if it can be fixed and noticed cache error :(

  • Kapil Arya

    ^^ You may try creating new user account or re-registering Store app: https://www.kapilarya.com/how-to-re-register-store-app-in-windows-10

  • I’ve been trying to get my Windows Store working for quite a while, I’ve tried every last thing you’ve suggested, nothing works. I tried other things I found suggested elsewhere, nothing works. If I create a local account and log into that I can download whatever I want, but two separate Windows Accounts are unable to download anything from the store on this machine (yet work fine one others).

    The only error I get is the extremely unhelpful “Try Again Later – Something went wrong on our end” notice. The handful of apps I already have downloaded still update as normal, I’m completely up to date with Windows updates. I disabled my anti-virus, my firewall, and I tried plugging my laptop directly into my modem in case my router was somehow running a VPN or something I’m not aware of.

    When I run the diagnostic tool it tells me it wasn’t able to fix my damaged cache, when I try to manually delete and replace my cache the LocalState folder is devoid of data. There’s a 193kb sessionstate file and emptiness. No matter what I do I can’t seem to get that folder to populate.

    ^^ Unfortunately, the last option you can try is to Refresh Windows 10: https://www.kapilarya.com/reinstall-windows-10-without-affecting-personal-files

  • Hello, I tried most of the methods out there, and my apps still don’t open, the Xbox services of auth don’t start in the boot (xblauthmanager & xblgamesave) , All started since (I think) I deleted the pagefile.sys on the partition I have windows, not the one in D. The folder in LocalState was empty, even creating Cache didn’t fix it. I logged to the store with another email and restored the store, didn’t help. Even deleting the folder of windows apps in REGEDIT sooo I can’t use 3rd party apps since weeks ago in my win10. Any ideas?

  • Kapil Arya

    ^^ For multiple issues, you should Refresh Windows 10: https://www.kapilarya.com/reinstall-windows-10-without-affecting-personal-files

  • even the option with refreshing windows 10 without affecting personal files didn’t help

  • Kapil Arya

    ^^ Try Windows 10 in-place upgrade: https://www.kapilarya.com/how-to-repair-windows-10-using-in-place-upgrade

  • Ran repair process described in Fix 1 and 2 on win 10 creators build for ‘Windows Store Cache may be damaged error. There was no existing ‘Cache’ folder and I created one. Rebooted, ran the troubleshooter and error still exists. Nothing was added to the Cache folder. Error still exists. Exploring further steps.
