Registration of Office 2024 and New Computer

I bought a new computer with Windows 11. I used LapLink PCmover to transfer data from my Windows 10 computer to the new one.

My new computer now had Office 2021, which I deleted to install Office 2024. I couldn't find how to register Office 2024.

I went to Microsoft for help and received an update that turned my Office 2024 apps into Office 2021. My Control Panel shows that I have “Microsoft Office LTSC Professional Plus 2024”.

Under devices, MS did not have my new computer listed and had Office 2021 listed as registered.

For several days, I have been trying to deal with MS to register Office 2024 and to list my new device. I have been directed to many sites that were supposed to solve both issues but have failed on each site.

Can someone give me some direction on how to solve each of these issues?

I will assume you have a Product Key for your Office 2024. If so, does this site accept your key? (Use the "Get Started" button).
Setup Microsoft 365

Thanks for the reply.
Yes, this was a new 2024 which was installed. I also have a Product Key which is the first time being used.
I went to the set your suggested and entered the Product Key. The next screen offered the downlload.
I have already downloaded Office 2024, so I just need to register it.
It seems that the poblem is that MS does not recognize my device ahd refers me to my Windows 10 which had Office 2021.
MS has that Office register and then changes my Office 2024 files with an update that changes my apps to Office 2021.
It would seem that Ist line of business is to register my device which should then allow me to register Offic 2024 to that device.
How do I register the device. What I have tried through MS, jsut did not work for the new device.
Can you suggest a method to register the window 11 device?
