Hi Nick,
Do you mean the message that states that your hardware has changed and that you need to re-run the assessment? If so, that is the message I got when I had first installed the driver, which is what I expected (and, indeed, the same message I have received from the tool upon every graphics driver update). The message did not appear after I had run the tool the first time. This is the first time that I have had to run the tool twice, and I haven't done anything different as regards the driver installation than what I normally do.
