Windows 10: Activate Windows 10 Pro

I am having trouble activating my "Windows 10 Pro" on one of my Dell XPS 8930 desktop computers. Both computers were received with Windows 10 Home. One of the computers activated correctly. I purchased Windows 10 Pro at the Store.

The error I am receiving is:

"We can't activate Windows on this device as the previous version of Windows was not activated prior to upgrading to Windows 10. Go to the Store to buy genuine Windows. Error code: 0x803F7001

Troubleshoot returns "We can't activate your copy of Windows.

What should I do?
Thanks

:)

Can't upgrade from Windows 10 Home to Pro

Hi Bill,

I suggest you to download and create an installation media for Windows 10 Pro form the link provided below:

After the installation media is created, suggest you to upgrade to Windows 10 Pro from the installation media. When the upgrade asks for product key, enter the product key purchased for Windows 10 Pro. If it does not accept, suggest you to skip the activation
step. After the Operating System is installed, suggest you to activate by phone by following the steps below:

• Press “Windows key + R” and type “slui 4” and press Enter.
• Select the Region from the list and click Next.

Windows 10 Activation (Insider)

How long did you wait for activation?
When I re-installed with a fresh install... it took a few hours to sync and activate.
However, it did, finally, activate.
