If you thought we’d have any further insight into Windows 11’s new error code, 0x8007007, which is happening during install, you’d be wrong. With such a generic error code and no real way to parse what it means, it’s become a bit of a head-scratcher for those trying to update onto the new OS.
We’ll keep this post updated for the future, as more information comes out about it, but for now, you can try the methods below and see if that helps out at all.
Run as Administrator
That’s right, just right-click on the installation assistant and you can probably get this to run.
Multiple people on Reddit have said that this fixed their issues, making us believe it could be something to do with the various permissions needed to begin the installation process sometimes not being present on the base level of Windows.
Restart the Installation Assistant
It’s a meager attempt at an answer, but honestly, this fixed it for us in the office. Whatever hang-up Windows 10 was having with getting the installation going for 11, this jostled it back into working order. When you do restart it, try running as administrator too.
Go for the nuclear option. Some are believing it to be related to drivers colliding with whatever the Installation Assistant is attempting to do, so it might be best to nuke your system and start again.
Obviously, you’ll need to back everything up before this, as you’re absolutely going to lose everything if you do. When the Assistant pops back up, tell it to do a clean install.
