hello all, I am trying to install a Quadro P400 on a win10 x64 pro computer. Every thing appears fine until I go to install the drivers. I get the 'incompatable with your system error'.
It had an ATI firepro V4900 in previously but that has failed, hence the need for a new card.

I have tried everything I can think of, old drivers removed etc...

PS, I have tried to install the same drivers on another identical computer and this installs correctly.

Thanks in advance.
