Sorry Your account is unable to make this type of purchase on Xbox.com. Please complete this transaction from your Xbox.

I checked and both website and console are in UK region

This is the exact message I keep receiving:

Sorry

I am having the same issue. I have tried time and time again and all it keeps saying is: Sorry

Your account is unable to make this type of purchase on Xbox.com. Please complete this transaction from your Xbox.

any news on how to fix this @microsoft

Hi, this isn't so much an issue on the store as the way that the Xbox One store and Xbox 360 marketplace work.

If you take a look at this link http://support.xbox.com/billing/payment-and-purchases/troubleshoot-xbox 360-marketplace-purchasing

In particular this section........

I'm getting the message "Your account is unable to make this type of purchase on Xbox.com. Please complete this transaction from your Xbox."This error means that the Microsoft account that you're trying to use to make the purchase doesn't have the ability
to make the purchase.
Child and teen accounts are prevented from making purchases in the Xbox 360 Marketplace. Changing your Microsoft account age or your purchase settings won't resolve this issue.

To resolve this issue, purchase or download the content on your Xbox 360 console.

The backwards compatible game can only be purchased on a physical Xbox 360 console if your account is a child or teen account. If you know someone who owns or have an Xbox 360 console yourself you can make the purchase on the 360 and it should then show
in the ready to install section on your Xbox One system.
