I think I know the answer, but please clarify what you were running on your 3 machine at their upgrade times. I think it was 2 64-bit Win7's and 1 32-bit Win7--all upgraded to 64-bit Win8. ... You said something about all the product keys being the same. Please clarify that too.How could you do that?I upgraded three PCs to Windows 8 Pro. Two were 64-bit and one was 32-bit. I used the 64-bit ISO from one of the 64-bit systems to do a clean install on the 32-bit system, so all three are 64-bit now. The product keys are the same for both.
Each time I upgraded one of my PCs, I downloaded the ISO for the upgrade, which is the same as the full install disk. After upgrading one of my PCs (the one that had the 32-bit version of Windows 7), I did a clean install with the 64-bit disk. All three of my PCs were upgraded to Windows 8, the clean installs were performed using the 64-bit upgrade disk by booting to the disk and starting a clean install. Once complete, you may receive the following message when trying to activate:
"Code 0xC004F061" Windows cannot be activated due to not being an upgrade.
1. Launch the command prompt as an administrator (Windows key & X –or CMD X if running on a Mac).
2. Type regedit and press enter.
3. Navigate to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Setup/OOBE
4. Look for the item MediaBootInstall and set the status to 0
5. Close regedit and head back to the command prompt that should be still open.
6. Type slmgr /rearm and restart when prompted.
You will have an activated clean install of Windows 8.
You mention that the ISO's yielded, in effect, full-install discs. Did you try a clean install where you formatted prior to using one of your created discs. On which type of installs did your receive "'Code 0xC004F061' Windows cannot be activated due to not being an upgrade?" 64 bit to 64 bit, or 32 bit to 64 bit.
