  1. Missing "api-ms-win-crt-heap-l1-1-0.dll" File On Windows 10


    Hi


    Recently I installed a program that requires the "api-ms-win-crt-heap-l1-1-0.dll" file which I've heard is related to Visual C++, which makes sense when the program in question has a requirement for Visual C++ 2019 listed. Funny part about it is that I have Visual C++ 2015-2019 installed, both x64 and x86 versions. I've attempted reinstalling them, with no luck. How I know I'm missing this specific file is because the log for the program says that it's missing said file upon startup, so it cannot run.


    For some quick specs, I'm running Windows 10 version 20H2 OS build 19042.746 which is fully up to date. For a CPU, I'm running an Intel Core i7 7700K.


    I've tried everything I can think of to fix this issue myself, but I haven't gotten very far unfortunately. Various sources for this file online are all unofficial, so I'd prefer to stay away from them and get something from Microsoft if I had to. Ideally, it would be nice to fix this issue with what I have installed as I shouldn't be missing this file with C++ installed, but somehow I am.


    Any ideas on a possible fix?


    Thanks.

    :)

  2. 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    said that Dependency Walker is obsolete and these names are not real dlls, but some kind of indirection.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?

    vcruntime140.dll, api-ms-win-crt-heap-l1-1-0.dll, api-ms-win-crt-runtime-l1-1-0.dll are missing!

    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.
