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!

    When you get the error do the below copy/paste (replace) and hit Retry.

    Copy and Paste (replace) wimgapi.dll from your regular C:Windows/System32/wimgapi.dll to C:Windows10Upgrade/wimgapi.dll

    Good Luck

    Thats weird!  I found the file on my C disk with no problem?  Hmmm...seems to me the file should be on the install disks yeah, but that'll be a pain in ass unless you can do some sort of search of the 7 install disks - yeah.  

    Listen - I am no expert here with this stuff.  I am sure there are many more MORE qualified people to answer your questions.  Not trying to get rid of your comments - just don't want to steer you in the wrong direction.  Let me know how it goes!

    I would try one more time though - on the regular computer C drive - lookimg for that file.  I do not know HOW it couldn't be there?  You ran the 10 update until it errored out - right?  THEN went lookimg formthe dll file?

    Good luck & again - Let me know how it goes!
