Windows 10: Windows Pro to Home - Invalid Product Key

I recently purchased a license of windows 10 home. Following the purchase, I received an email containing a link of an installer which downloads windows setup.

The problem I’m facing is that the installer downloads windows 10 professional setup while my license is for home edition. I learnt this after installing windows and being unable to activate it.


How can i get the Windows 10 Home installer with correct license?
