  1. Missing api-ms-win-core DLLs - OFF Network Machine


    Hello,

    I am building an off-network test station that will run Windows 10. However, the software it'll be running needs the api-ms-win-core DLLs there was a very long list and they are showing as "missing." Because I cannot plug this up to the internet and do a Windows update or anything, how might one acquire these items? Is there a place to download them? Do I need to register each one or is there a happier faster way to do so? The Windows 10 version is 1909.

    :)

    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?

    Missing api-ms-win-core DLLs - OFF Network Machine

    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?
