Hello, all. It a month already counts when I’m not able to use Windows Store. I can open it and download some of the apps, but sometimes either the download or installation process fails with this error: “Something bad happened. Unknown layout specified in manifest.”
I tried installed Windows Updates, but in vain, tried clearing Windows Store cache, and ran the Troubleshooter for Windows Apps. None of these fixes helped. What else can I try?
For the last couple of month, Microsoft Windows community members keep reporting an error “Something bad happened. Unknown layout specified in manifest.” The bug falls into the category of Windows Store[ref en-1] errors due to the fact that it occurs only when accessing Windows Store.

The error emerges without an apparent reason (no updates installed lately, no software installed/removed, no virus infection, etc.). Nevertheless, Windows Store stops providing the service.
“Unknown layout specified in manifest” error blocks both downloads and installation of new apps, as well as updating Windows OS and already running apps. Nevertheless, Windows Store and apps provided on it can be accesses as usually.
Microsoft has already officially acknowledged the error and promised to fix it with the upcoming update. One of the moderators reported, that the bug is in Windows 10 V1703 and V1709.[ref en-2] The manifest for the Windows Store seems to be different from the OS regional settings. Therefore, changing the location to US may help temporarily.
Few Microsoft community members approved this fact by saying:
I’m in Panama but the language, region and time zone all had to match. Set it all to US and everything works.
Just changed my region country to United States and it works like charm.
I set my Region and Language settings correctly and that fixed the problem for me.
If changing Language and Region settings did not help to fix “Something bad happened. Unknown layout specified in manifest” error, we would recommend checking the system for corrupted files, clearing Windows Store cache, and resetting the Store app. The instructions are provided down below.
NOTE: if none of the fixes worked, the only solution is to wait until Microsoft releases the patch update.[ref en-3] If, unfortunately, “Something bad happened” impacted the Windows Update service as well, you will have to install the update manually from the official Microsoft’s website.
Method 1. Change Language and region settings
If you were out for holidays in another country, your region might have been automatically changed to the location where you’ve been settled temporarily. Sometimes, people change the region by accident, so to fix “Something bad happened. Unknown layout specified in manifest” error on Windows Store, change the region to US.
Sometimes, setting the region back to normal (e.g. Germany, UK, Spain) also helps. However, note that this fix is temporary and you should opt for the official fix as soon as Microsoft releases it.
- Press Windows key + I and select Time & Language.
- Open Region & Language section and check if your Country/Region is set correctly.
