Don't put edition ID and run it from /Sources/Setup.exe It'll ask for version Code: [EditionID] [Channel] Retail [VL] 0
I officially think the EI.cfg trick is broken. Does not work even when running from \Sources\Setup.exe. I am trying this with Windows 8 Pro with Media Center though so maybe just a regular Windows 8 Pro will be different. I'll test and report.
That's the odd thing. Boot from Media clean install is fine. Upgrade, totally broken. So now instead of an AIO we need 3 discs... An AIO Clean Install, x86 Upgrade (Requires Key), and x64 Upgrade (Requires Key).
You can't upgrade if your base OS is not the same language as the newer OS. You can keep only personal files in this case, maybe that's the problem ? If you don't put ei.cfg, you'll can chose between "keep nothing" or "keep personal data" if you run the root setup.exe
That's correct however because AIO discs use both x86 and x64 setup files modified and the EI.cfg method is broken for upgrading it makes the AIO less useful that it used to be thus now the requirement to have an AIO for clean installs and a seperate x86 and x64 disc for upgrades.
Actually it is possible. I just did it on a VM. You have to add the Windows 8.1 Pro with Media Center image as an install option to the install.wim then use a WMC product key when upgrading.
That's the problem with not using your own key to install. Which is probably why I remember having problems doing this... What you can do is install pro, activate, upgrade, activate, then save the data.dat and tokens.dat from the spp\2.0 folder and replace them on a new install of prowmc, much the same way we did for 8.0
Well the issue for me is I don't have a valid 8.0 key to activate with. I used the Install, KMS Activate, and then Upgrade using free WMC to get Windows 8 Pro with Media Center. Need to find a way to activate without a valid Windows 8.1 Pro activation.
Well I have confirmed that EI.cfg is broken 100% when it comes to upgrades. Anyone else able to get it to work?
