Windows 10 and 7 Pro OEM activation

Hi,

From what I understand the Win 10 Pro OEM key can be used to activate Win 7 Pro OEM. Bascially I have a request to build a PC with Win 7 Pro, as this is need for the software used by the business. I have run out of copies
of Win 7 Pro OEM.

I've tried using a Win 10 Pro OEM key for a Win 7 Pro OEM activation, but it's not working, tells me the key is not valid. Am I suppose to install Win 10 pro OEM, activate it, and then install Win 7 pro OEM, and activate
with the same key. I'm still getting orders for PCs with Win 7 Pro, and finally run out of copies.

What is the correct procedure to activate an Win 7 Pro OEM install with a Win 10 Pro OEM key?

Thanks
