Error 0x8007007E during Windows 10 Update

[jdrbr549]

I have this trouble as well. Seems the new version is looking for a .dll that is only part of Windows 8. I do not have access to another machine as this is a machine that had an SDD failure. I've replaced the SDD and installed windows 7. I'm going to give this machine to my mother for christmas and she needs to the accessibility features (magnifier)

I'm currently downloading slower than before, which seems like it is working. You do not need another machine.

- Delete for Windows10Upgrade folder
- Take the file from Job48
- Disable your network (so his file doesn't get updated)
- Run the downloaded file
- Once past the agreement, enable your network

That's it!

Ive tried that 3 times myself, and I'm still getting the error

Well, I shared the older version with a couple folks who reached out and they said it worked for them so here's a working alternative temporary link to the one embedded in a post from someone else. This is a media fire link for anyone else who may need it so they don't need to email me directly:

media fire dot com + /file/mvt5dbd1cz89e4v/Working-Windows10Upgrade.zip

May get taken down/removed if it gets downloaded a bunch. Hopefully Microsoft will release a fixed version soon and before that happens. Scan and validate at your own risk. This is not any W10 code.

Mods: My apologies if I missed a rule about this, if so, please go ahead and delete / remove and I won't repost.

This is working for me now, thanks for the old file.

Same issue. Already tried this method. It downloads to about 80%, it says installing from 80 to 99 and when the time comes to reboot and actually install the OS, I get a "Something went wrong" with error code 0x80004005. Googled that, I apparently need to stop wuauserv, bits and cryptographic services, rename a bunch of folders and try again. I'll try to do this tomorrow.

Btw, is there a way to skip the download all together? After the first error, I found the ESD image, converted it to iso and was, but it asks for a w10 key.

If you don't disable your network before/when you run the program using the posted old version, the first thing it does is check for a newer version and update itself, it then silently restarts and you'll have the same issue. So, as others noted you have to delete the contents of the original folder (or just rename it), then use the older version posted here in it's place. Make sure you disable your network (unplug from back of PC/wall/wifi or disable in network properties). Once it gets to the part where it's going to download the code you can (and must) re-enable the network.

If you already downloaded the install file (large 2.7GB file in that folder) you can put it in the older/working version and save the re-download time.

If you already tried all that, maybe a different issue.

might be worthe mentioning, you have to uninstall the Upgrade assistant from the control panel before running the other file.

If for any reason the download link provided does not work, i have hosted it onto my business website at CRS Norwich.

can be downloaded from: crsnorwich.co.uk/downloads/Win10Upgrade.zip

 

[willsmill]

sedace Thanks for your response. Yeah I have tried that exactly as laid out but still get this same error. I tried the update a couple days ago and and made it further in the upgrade process. The upgrade ultimately failed though (usb device left in during install) I tried to upgrade again today but have been unable to get pass this error after it verifies the download. I also had some windows updates this morning too. I've uninstalled those and am trying again

 

[alcheval]

Also, if the download crashes, then, the upgrade assistant updates itself and you have to start over.

Worked for me. Did the start/off network/back on network.

I reinstalled the OS last night and fought updates all day. So glad I do backups. Went back to pre-reinstall and kept things clean.

Thanks

Replace C:\Windows10Upgrade\wimgapi.dll with the one from C:\Windows\System32\wimgapi.dll

Tjohooooo, working like a charm, thank you!

Here's the copy that worked for me (make sure network is disconnected until the actual download starts)

MEGA

 

[antario]

does anyone have the ESD file and can upload it somewhere? I have a shitty 20 mbps connection on site and it takes ages to download

 

[insanityinside]

Just wanted to say thanks for the download - the bug was driving me nuts, but with a bit of fun and games (was fixing this remotely for a friend!), I got it up and running.

If you have already gone through the download and got the .esd file in the folder, if you unpack the zip file into c:\Windows10Upgrade overwriting the existing executables, disable the network connection / disconnect from the network, and run it, it works perfectly well with the latest version of the Win10 image, without having to download again. As mentioned earlier in the thread, as long as it gets past the checking for an updated version of the Windows 10 installer, it'll work fine going onwards, but will complain bitterly if it doesn't have a network connection after the initial check.

(I ended up writing a batch file to use netsh to disable the network connection, running the upgrader, waiting for 60 seconds, re-enabling the network connection, and then remoting back in to finish the job... nothing quite so fun as knowing you might not be able to reconnect afterwards!)

Edit: Typically between me hitting reply and typing that up, jpopo replied with the proper solution. Glad the reason has been nailed down!

Replace C:\Windows10Upgrade\wimgapi.dll with the one from C:\Windows\System32\wimgapi.dll

(Error while upgrading to Windows 10

As jpopo already said, the solution is
replace C:\Windows10Upgrade\wimgapi.dll with the one from C:\Windows\System32\wimgapi.dll

sedace: Thank you for your help and your download. The update worked beautifully after I uninstalled the windows 7 updates had installed on the morning of the 19th. I'm now running on windows 10. Thanks again.

GOT IT

Download attached file. If any previous folders in C:\ for Windows10Upgrade - delete whole folder
Disconnect network, either unplug ethernet or airplane mode for wireless
double click on the attached file. It will create the folder and attempt to update the app.
It will timeout after 5 seconds or so. When it gets to downloading the update, plug ethernet back in
Sit and watch the download happen, verify, and install. Worked on 32bit Win 7 Pro.

Job48's downloadable ZIP file did the trick for me.
Thanks!
