Have I bought wrong win10 license?

[wesley]

Hi guys

We have 2 dell Inspiron laptops at work..they activated as win10 Home Edition. We need out them on Azure active directory. So I bought 2 X Win10 Professional OEM. Cost £125 each

Opened one of DVD, tried the first key and it didn't work. Got error code 0xc004f050.

Should it be the retail one?

Thanks
