I recently installed the latest driver update, did a fresh install removing the old one before installing the new but I noticed that under custom install it showed Microsoft Visual Studio C ++ 2012 x86 and x64 as not currently installed or available for install and also Microsoft .net framwork 4.5 not installed or available for install, however they are both installed currently and up to date, is this something to be worried about?
havent noticed anything wrong running games/surfing web etc it seems to run everything fine its just odd that it showed them as being not installed when I can literally see them installed.
Well you could still do the steps i mentioned before.
But to be honest u dont need to care about it as long as it does not affecting your PC (btw if your those progs would not be installed/functioning you could not play most games)
So i suggest you leave it be untill the next update
