An unsupported processor has been detected, Why?

I am trying to install my Norton 360 on my new AMD Ryzen 9 8945HS with windows version 23H2 and I get this:

"# Message: “An unsupported processor has been detected. This version of the product requires a processor that supports the SSE2 instruction set…”

The newest version of our Norton product (22.x.x.x) requires SSE2 compatibility to run and does not support your current hardware. We have detected that your computer is running an older processor that does not support SSE2 CPU instructions. We recommend that you upgrade your computer with the latest hardware to enjoy the full protection of the Norton product."

Since this version of the Ryzen 9 came out in Dec 2023, I don’t think it is “too old.” Why should I get this error?

Its supported with Windows 11 as shown in this article. Norton shouldn’t be giving that error. Is there a trial version of ANY antiviral software on the computer? If so remove it and reinstall Norton 360.

Are you installing the Windows Store app version or the full install of Norton 360 from within your account subscription.?
