Windows 8.1 install


New Member
Hi All,

I am trying to install Windows 8.1 onto a new hard drive that is attached to a computer that already runs Windows 8.1 x32. I downloaded Windows 8.1 installation from Microsoft and made a bootable USB.

When I type in the Product Key, I get the error code "The Product Key entered does not match any of the Windows images available for installation. Enter a different key."

Using ShowKeyPlus preview, to check the version that my key is for. It said "Win 8.1 RTM ProfessionalWMC Retail".

Three things:

I am trying to install x64 (computer can handle it) instead of x32.

This key is from an upgrade xp to 8.1. But I did not get the typical error message saying that it is an upgrade that most users get.

The installation does not start, it wants me to place the key in first.

Any help or advice you can provide is greatly appreciated.

If the computer came with Windows 8.1 then it's most likely an OEM license. You'll have to get the restore disc from the manufacturer. You won't be able to use the retail version of Windows 8.1


If you are upgrading from XP to 8.1 then it means you have to buy a genuine license from the retailer.
You will have to buy a fresh Non-OEM license for your Windows 8.1 copy.

Otherwise, you would not be able to install Windows 8.1 on your system.
