Problem to redeem a gift code of Minecraft Windows 10 edition

I am trying to redeem a Minecraft windows 10 edition key from the Mojang website.

This is the prompt I am trying to redeem from:

--------------------------------------------------------------------------------------------------------------------------------------------------------------

Minecraft for Windows 10

You bought Minecraft: Java Edition during a period of time when Minecraft for Windows 10 was included for free. Claim your redeemable gift code by clicking the button below and follow the instructions. As you
might have guessed, Minecraft for Windows 10 can only be played on Windows 10.

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

It allows for users who have purchased the java edition of the game to then redeem a code for the windows 10 edition of the game.

This is the error message that pops up:

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Error! It looks like we've temporarily run out of gift codes for Minecraft for Windows 10. Don't worry though, more codes should be on their way. Please check back later!

Thanks for any help!

Hi
CuleSKY,

I'm sorry to hear that you are experiencing license issues with Minecraft Windows 10 edition. It's possible that you never actually redeemed the gift code that you were given. The date showing is when you claimed the gift code but if customer support cannot
see the license, then you have not redeemed the license to your Microsoft Account you use to log in to Windows 10. As you can also see, Minecraft Windows 10 edition is not listed in your games section of your Mojang account.

I recommend clicking where it says Redeem on your Mojang account and follow the instructions you see on screen.

If you have Java Minecraft, sign in with your Mojang Account on the Minecraft Website, and you should get an offer to redeem a code for the Windows 10 Version.

However, it was long ago since I did that, and don't know where exactly you need to go.

After you got your code, you can go to the Windows Store App on your Windows 10 PC and redeem that code in the Store App to get Minecraft Windows 10 Edition.

EDIT: It seems that you need to have purchased the Java Edition before Oct. 19th 2018 to be eligible for getting Minecraft Windows 10 for free.

Hey Nikolio16,

Minecraft: Windows 10 Edition runs specifically on Windows 10. If you would like to play Minecraft on Xbox One, you will want to take a look at Minecraft:
Xbox One Edition. If you would like to install the Windows 10 version of Minecraft on your Windows 10 PC, sign into the account that originally redeemed the code and download through the Windows Store.

Hope this helps!

This is quoted directly from Mojang's "Minecraft for Windows 10" support article about the process to
redeem this code, "Players who have purchased Minecraft: Java Edition before October 19th, 2018 can get Minecraft for Windows 10 for free by visiting their Mojang account. Log into
account.mojang.com, and under the “My Games” heading you will find a button to claim your gift code. If you purchased Minecraft: Java Edition after October
19th, 2018, the button will not be there, so if you’re unsure of when you purchased Minecraft: Java Edition, that’s a good way to check. Pressing the button will generate a token and send you to a Microsoft redemption page."
