Windows 11 home to windows 11 pro unable to activate

I just finished upgrading to windows 11 home from windows 10 home and decided I would like to purchase windows 11 pro. I used the link in settings to upgrade my version of windows. I bought the 99 dollar windows pro from within the Microsoft store. It showed the purchase was successful and a button appeared saying install now.

When I clicked the button it said it was unable to download and to try again. Every time I would click I would see the same message and nothing would happen.

I restarted my computer to see if that would fix the issue. As I restarted, my computer said it was performing updates. When it finished performing updates, my computer turned back on it now how's that I have windows enterprise installed and it will not let me activate. The trouble shooter does not work and it displays the error code 0xc004c003.

My my Microsoft account shows my purchase of windows 11 pro but it doesn't give me an access to a product key. When I click on more details it takes me to a broken link within Microsoft website saying this page no longer exists.

Any ideas on how to fix this so I can activate the correct copy of windows?

Thank you for the help!

    I found an answer on another form. Thanks to Lester BernardReyes.

    It is a known issue. All that I needed to do was change my product key under the activation tab in windows settings to a default key.

    I used this key VK7JG-NPHTM-C97JM-9MPGT-3V66T

    It then asked me if I would like to activate my copy of windows. I said yes and then it changed from windows 11 enterprise to windows 11 pro.

    Hopefully someone else will find this helpful.

    I buy my license on the Microsoft site. They said that the product key is on the mail sent when I bought the license buy it doesn't. and in the order history doesn't appears the product key. I'm asking for every possible way to get my product key, my actual windows is a home ed, but I need some features of my pro version.

    I want to upgrade but without my key is impossible. I already have my ms account associated to my login and is an administrator account. the only way to upgrade it is using the key or buy a new license (is totally illogic buy a new license to get my old license...) and nobody answer from Microsoft. the only thing the have is a troubleshoot step by step that goes in circle. Is sooooo hard to them give me my already bought key?

    I can't get that key from my old computer, because it was broken, I sent to be repaired and ordered to use the OEM version windows. So the windows pro license installed is free to use.

    I'm reaching hating levels with MS right now, 2 weeks going around without any luck.
