missing api-ms-win-core-libraryloader-l1-1-1.dll preventing me from upgrading to windows 10

Anonymous

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!

Try replacing C:\Windows10Upgrade\wimgapi.dll with C:\Windows\System32\wimgapi.dll.

Error message was: "api-ms--win-core-libraryloader-l1-1-1.dll is missing"

This worked for me also.

I copy and paste wimgapi.dll from C: Windows/System32/wimgapi.dll to "Windows10Upgrade" folder.

Thanks Burnett

Sorry, I guessed at the date. My point was it was older. Might depend on your system too. Whatever it worked nicely. Too bad you can't depend on MS for a clean upgrade.
