Windows 10: api-ms-win-crt-heap-l1-1-0.dll

I'm looking for file api-ms-win-crt-heap-l1-1-0.dll. Reinstalling the Microsoft Visual C++ 2015-2019 Redistributable for x64 and x86 didn't help.
Should a dll with this name really exist, or is the problem somewhere else?
There is a file of this name at

C:\Windows\WinSxS\x86_microsoft-windows-m..namespace-downlevel_31bf3856ad364e35_10.0.18362.1_none_3da3af2845f54b85


Here are some more details:
I am trying to install a python pyd file using python import. The pyd file was created by python pip install, which used python setuptools and compiled and linked a large number of C and C++ files using Visual Studio C++ 2019 on my computer, which was installed as part of Visual Studio Community. So, if I create and install this using the same instance of Visual C++, I wouldn't expect to get this kind of problem.

The pyd file is very similar to a dll file. As a first step, I used Dependency Walker to check for dependencies. It found a very large number of missing dependencies with names like api.ms-win.xxx.dll and ext-ms-win-xxx.dll, but a post on StackOverflow said that Dependency Walker is obsolete and these names are not real dlls, but some kind of indirection.
https://stackoverflow.com/questions/36240215/dependency-walker-missing-dlls

Then I used dumpbin.exe, which I found in

"C:\Program Files x86\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.26.28801\bin\Hostx64\x64\dumpbin.exe"

Dumpbin reported the following dependencies:
libopenblas.dll
python37.dll
MSVCP140.dll
KERNEL32.dll
VCRUNTIME140_1.dll
VCRUNTIME140.dll
api-ms-win-crt-heap-l1-1-0.dll
api-ms-win-crt-stdio-l1-1-0.dll
api-ms-win-crt-string-l1-1-0.dll
api-ms-win-crt-runtime-l1-1-0.dll
api-ms-win-crt-time-l1-1-0.dll
api-ms-win-crt-math-l1-1-0.dll
I added the directory of libopenblas.dll basic linear algebra to the PATH environment variable and can now find the first 6 dlls using the "where" command, but I cannot find the remaining 6 "api-ms-win-XXX.dll", and a search of my disk produced the information reported above.

As far as I can tell, everything is 64-bit. I checked the pyd file using Sysinternals sigcheck. Windows and Python are also 64-bit.

By the way, when I run python import, I get

Exception has occurred: ImportError

DLL load failed: The specified module could not be found.

This can mean that the module we are trying to import is not found, or that some dependency within it is not found. It is like the "file not found" error message, which does not say which file was not found, and has annoyed me for over 40 years.

Are these files "api-ms-win-XXX.dll" real dlls? If so, how do I install them? If not, why are they showing up in dumpbin and where do I need to look for the cause of the problem?

Hello users,

From location is known, but that case is solve your matter from installation.

Now case is, .dll missing from opening installation/setup file locations or error opening .exe file or corrupted with other versions of game installations.

When your installation .exe file not open with your windows system or not read it properly then showing error message with popups in same windows. Then you try to download and setup from many kind of locations! Now here my example
is, simply try to download it from - Download Visual C++ Redistributable for Visual Studio 2015 from Official Microsoft Download Center that location.

Downloaded file depend on your systems build or architect as 32/64 bit.

It solve your,

vcruntime140.dll

api-ms-win-crt-runtime-l1-1-0.dll

api-ms-win-crt-heap-l1-1-0.dll

and also another two type of variation.
