Windows 10: I have a series of files on my desktop called 'api-ms-win-core-timezone-l1-1-0.dll'. I am...

I have this files on my desktop, and they overlap with my icons. I did the system update but they didn't go away.

Missing api-ms-win-core DLLs

Hi

I bought a laptop with Windows 8.1 and upgraded to Windows 10. It's a 64-bit system with an AMD processor. I'm trying to use py2exe to turn a Python script into a standalone executeable but I have missing DLLs. The list of DLLs is:

- api-ms-win-core-libraryloader-l1-2-1.dll

- api-ms-win-core-atoms-l1-1-0.dll

- api-ms-win-core-winrt-error-l1-1-1.dll

- api-ms-win-core-sidebyside-l1-1-0.dll

- api-ms-win-core-localization-obsolete-l1-3-0.dll

- api-ms-win-core-heap-l1-2-0.dll

- api-ms-win-core-heap-l2-1-0.dll

- api-ms-win-core-delayload-l1-1-1.dll

- api-ms-win-core-libraryloader-l1-2-0.dll

- api-ms-win-core-rtlsupport-l1-2-0.dll

- api-ms-win-core-shlwapi-obsolete-l1-2-0.dll

- api-ms-win-security-base-l1-2-0.dll

I do not know where to find these DLLs. I have installed the following in an attempt to resolve this but it has not worked:

- Visual C++ Redistributables (x86 and x64 - 2008, 2010, 2012, 2013 and 2015)

- Visual Studio 2010 Express

- Visual Studio 2010 Express Prerequisites x64

- Microsoft Windows SDK for Windows 7 (7.1)

Also Microsoft .NET Framework 4 Multi-Targeting Pack is listed in my Programs and Features list but I am unable to install ANY version of .NET Framework after 4. For example, when I try to install NEW Framework v4.6 the installer blocks and says I already
have a newer version of .NET Framework installed. But when I tried to install Windows SDK for Windows 7 the installer told me I had a pre-release version of .NET Framework 4 (which I don't remember installing).

Where can I obtain the missing DLLs from?

 

api-ms-win-core-libraryloader-l1-2-1.dll is missing

It is not *-l1-2-0.dll nor *-sysinfo-l1-2-1.dll but *-l1-2-1.dll that is missing.
I have a win8.1 Ent installing in Parallels Desktop on my MacBook Pro.
I'm trying to install a win10 on an external USB3.0 following the tutorial.
On the last step in Step 3: Deploy the Windows installation image, I try to create the boot section using:

but it pops up "The program can't start because api-ms-win-core-libraryloader-l1-2-1.dll is missing from your computer. Try reinstalling the program to fix this problem."
The windows installed in Parallels is 64bit, and the win10 I'm trying to install is also 64bit.

How can I fix this problem?

 

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

Code:

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.
Dependency Walker: missing dlls

Then I used dumpbin.exe, which I found in

Code:

"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

Code:

Exception has occurred: ImportErrorDLL 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?
