Download direct-X, should fix the problem.

iJT as said above you're missing DirectX so you should install that, link above is the official one.
To make sure this doesn't happen again with other redists you can also run this https://github.com/ChxseH/Redist-Installer/releases/download/latest/Redist-Installer.bat which will install all the required redists all at once (DirectX included)
