Windows 10: Win10 Home to W10 Pro Upgrade Error using Product Key

Hi all -

I'm attempting to upgrade a Dell W10 Home, x64 Laptop to W10 Pro, x64.
Using a couple of what I was told were legit keys, I receive this error after W10 accepts the key...





Activation software problem?

Any help appreciated.

Thanks,

upgrade from win10 home to pro using a win8 product key

Is this possible ?

Win7 home on an OEM pc.

I have a win 8 pro ( not 8.1 upgrade retail product key.

If I upgrade win7 hp to win10 home,

can I use the win8 pro retail key to upgrade win10 to pro

edition ?

 

Cannot upgrade to Windows 10 - Unique Product Key situation

No... let me try again.

• Old computer is running Win7 Pro (SP1) with a Product key I have from a few years ago. The Product is activated already, but I do NOT use this computer at this point, so I didn't worry about using the Product key when moving to the new computer (see below).
  
• New computer is running Win10 Pro, with data and OS migrated from the Old computer, (same Product key as above), then Upgraded to Win10 (without getting a new Product Key).

What I am trying to do now...

• I want to upgrade the OLD computer (Win7 Pro) to Windows 10... using a new Product Key I just purchased.
• I have tried to do this internally, and also using the ISO burned to a thumb drive. But it does not want to work.
• Steps:
  • Start from USB drive.
  • Enter New Product Key (or click "I don't have one").
  • Install initiates and then tells me to restart from Windows and then open the installer again to continue.
    • At this point, I actually need to Quit the installation to restart the machine.
  • When restarted, I go to the USB drive and restart/resume the installation process.
  • I have tried to download and not to download updates, but when the installation fails, I see the message, "Something happened" and "Setup has failed to validate the product key".
  • NOTE This happens if I enter the NEW Windows 10 Product Key, or if I skip that step (which I assume means that it will use the old Windows 7 Key for the upgrade).

 

upgrade from win10 home to pro using a win8 product key

I understand the upgrade path from retail or OEM .

What I want to do is use the free upgrade from win7 home

OEM licenses to windows 10 home licenses first.

Then upgrade the windows 10 home OEM version to windows 10

pro version; with the last step to win8.0 pro retail key

On the last step above, will the licenses stay on a OEM licenses or change to retail key ????

or is this not even achievable unless I do the install buy media, usb or dvd.

If that is the case than doing the same method from win7 to win8.0 pro would be a more direct route; but the issue is still if I can upgrade win 7 home OEM to win 8.0 pro with a retail

key??????

If that is the case neither route will get the end results win7 home to win 10 pro; unless at one time I do the upgrade with media, usb or dvd, wiping what ever previous operating system was installed before that one.

Win7 home to win10 home or win8.0 pro; then upgrade to win10 pro with a mix of OEM and retail keys.

Thanks
