Hi guys, I have a problem with my AIO ISO. When I use it to do an upgrade from Windows 7 and Windows 8.x, W10 is NEVER activated after update. Of course I'm using the same version (W7 Ultimate 64 to W10 Pro 64 and W8.1 Core 86 to W10 Home 86) and Windows licenses are official. I have the error code "0xc004c003" as a lot of people... (Key is blocked). Windows Store tells me the license is not official and wants me to buy a new one. - slmgr /ato never works. - slmgr /dlv indicates "0xc004f034" for "Notification Reason" (which sounds better than "0xc004c003"). With a DVD created with MediaCreationTool it works. Does someone have the same problem (I hope so...) ? Thanks .
Try this, this what i do if key is blocked: - check if windows 7 is activated (slmgr /xpr and slmgr /dlv) - use internet explorer to go to microsoft.com/genuine/validate.aspx and validate windows - as soon as it says windows is genuine, you can start upgrade to windows 10 (inside windows 7 start setup.exe) - do not forget that you need a working internet connection for windows 7 and windows 10 or it will not activate
It happened me once; it was because I disconnected the computer from network while upgrading. Doing the upgrade again on the same machine, but keeping it connected, ended successfully.
Thanks. The computers are connected to network and Windows is genuine. When I use the "corepro" ISO from MediaCreationTool it works. It's only the AIO ISO which has a problem.... .
It's already proved that upgrading using ISO will give you permanent activation. As you said, there should be an issue with your AIO. And, in many places I read that, AIO's are only for clean install and not for upgrades.! But, don't know about yours.
Yes I've already read too that AIO couldn't not upgrade but I don't understand why it would not... It's only with Windows 10 activation because with Windows 8.1 it works.
Maybe there's a kind of signature somewhere in the WIM file ? Did you already try to make a WIM file containing all versions using an existing WIM ?
Found ! We have to delete ei.cfg. Windows is clever enough to detect the Windows version to upgrade. No problem in boot mode, just choose "ignore" to license key and you can choose which version to install.
