So - this is a clean install on a new machine (I got fed up of the VM taking 4 cores and 16GB out of my workstation). Win7 x64 SP1 with all the updates. 8210 fails to install complaining about KM3033929. Searched the forums and saw the /noSHA2check workaround - only it doesn't work. Well it installs but doesn't function. I get a 'Windows needs a digitally signed driver' error and the DVD drive isn't found. See attached screenshots. I've done the 'uninstall, restart, reinstall, restart' gig a couple of times to no avail. It's a reasonable chance that I screwed something up - but I can't see what.
