api-ms-win-core-localization-l1-2-2.dll missing

What is the complaining program test2.exe?

Is that something you are composing or got from another source - regardless you should ask the author where to get the APIs and DLLs necessary for the executable to run.

Describe how you searched "everywhere".

I did a google search and found another topic of yours here:

https://forum.qt.io/topic/97270/api-ms-win-core-localization-l1-2-2-dll-is-missing-from-your-computer-in-windows-7/2

Since you did not specify where you searched "everywhere" I did another Google search and found plenty of places to download but don't know if they are trustworthy but I downloaded one anyway and it looks like a Windows 10 file:

Then if you check this article on Microsoft:

https://docs.microsoft.com/en-us/uwp/win32-and-com/win32-apis

It also says it is a Windows 10 API:

But you says you are running Windows 7 so something is not lining up in your environment.

Hi,

i am composing this app in QT .and compiler is visual studio 2015. 

By everywhere i meant on internet and offline sources. 

is not available on internet .Previous version of this dll i.e...l1-1-1,l1-2-0 are there but not this one.

My compiler is using windows 10 SDK .Thats why it is asking for this dll(as i think).

Sure it is available on the Internet because I found it, downloaded it, and showed you the version information in my earlier reply.

Is the one I downloaded a legitimate Microsoft file?

Is the one I downloaded the one you need?

Is the one I downloaded going to resolve the issue?

I have no idea but from a Google search you can see where I downloaded the one I referenced:

That is about all the assistance I am going to be able to provide since I have no way to test that to see if it is right.

If nobody has any other ideas I would pursue the other topics you ave running in the other online development communities.

hi,

again the dll i need is api-ms-win-core-localization-l1-2-2.dll and the one available on internet is api-ms-win-core-localization-l1-2-0.dll

both are different.

I see - my bad.

I'm not going to do any more homework or Internet searches for you so you may want to take a look at this page:

https://docs.microsoft.com/en-us/uwp/win32-and-com/win32-apis#apis-from-api-ms-win-core-localization-l1-2-2dll

Maybe somebody smarter than me has some other ideas.
