i tried re-install, downgraded for lower version from the latest version, rebooting windows but it still not works.

because of my poor visibility about it, googling did not helped for finding the reason all by myself.

i would like to ask how can this be resolved if you can.

it was about visual studio c++ issue, it is resolved after re-installing it.
