Can't get Nik 4 to work on new PC

Hi there, my first time here, I’ve had Nik suite in it’s various forms for years but sadly my PC bombed out and had to be replaced. I’ve got the replacement working working but yesterday paid just under £90 for the latest version but after download just can’t get Nik working it’s present in the file list within PShop but not to be found in the plugins list within Photoshop. I’m missing Nik greatly any suggestions please ??

Have you a folder google in plugins’s folder ?
C:\Programmes\Adobe\Adobe Photoshop CC2021\Plug-ins.

Franky, if I have I certainly can’t find it !
