Razer barracuda x headset not registering even though serial number is detected as it puts in the puts in the product code itself.

I got the headset today. just wanted to activate the 7.1 surround but when I try to register it says unfortunately this product is not eligible for registration. I only tried to register because the guide on the paper that came with the headset said to do so. I dont know if its because im on windows 11 now or not but it did also say on the paper only eligible for windows 10 64 bit and above. I did not buy from another retailer it was amazon with the razer link being there linking to their other products. what should I do? thank you in advance.
