DirectX Runtime out of date?

New computer, new Hardrive.
Tried launching Gmod, it gives me the error “Your DirectX Runtime is out of date. Download and install this file from Microsoft” To which it opens the Download Windows 10 page…very useful considering i already have Windows 10. :goodjob:

dxdiag says my Directx is version 12
steam says it’s version 10

?
