I tried the auto driver download thingy in Vegas Pro 18; it correctly saw my driver was out of date but the one it downloaded was the desktop version not the notepad version (the latter being what NVidia themselves say to download).
What the difference is, I have no idea, but they are different files with different file names albeit of the same numeric version of the driver.
Thought I'd mention it so Magix can sort it and in case it causes any issues.
