I'm currently on windows 7 and whenever I run Windows 10 upgrade assistant it gets to 99 then tells me I'm missing api-ms-win-core-libraryloader-l1-1-1.dll. I've tried running it on a clean boot, I've ran system cleanups to repair any corrupt files, I tried removing my antivirus, and still it won't work.

Does anyone have any other methods to fix so I can upgrade? any help appreciated!

    I had the same "api-ms-win-core-libraryloader-l1-1-1.dll" missing issue 

    when upgrading Windows 7 to Windows 10 

    and finally I saw your post and tried fixing the problem 

    by "Replacing 

    C:\Windows10Upgrade\wimgapi.dll with the one from C:\Windows\System32\wimgapi.dll". It works.
