Cuda toolkit installation fails: "core update failed"

Hello, I’ve been trying to install CUDA toolkit 10.1 (any release) or 10.0, after upgrading the Nvidia drivers to 441.12 and installing visual studio 2015 and 2017 but always hit the same issue: the installation of CUDA fails always when it reaches “update core”. My computer is a windows 10 with two P4000 Quadro nvidia cards.
I’ve read multiple threads and forums but can’t find anyone who had a similar issue. Any help greatly appreciated!
