Do you see the three "Notebook" items ? Do those appear for you ?

I don't see that three "Notebook" item. On the NVIDIA GeForce
Experience panel there is a download button. I always have downloaded
pushing that button without problems but now when I click on that
button, it opens the download but this download is unabled.
