@Ari204406 The driver for your graphics card is over three years old. You can download the newest version from Intel:

If that alone doesn't help, you really do need to install DirectX, not just download it.
I'm not sure what the person you talked to meant about not downloading the file, but it's perfectly safe to download from Microsoft or other manufacturers' websites (like Intel's, in the link above). That's the only way to get the newest updates. And since Windows 10 updates automatically, your other software needs to be updated as well to remain compatible.
Once you've installed the new driver and DirectX, try to launch TS3 a couple more times, and if it still doesn't work, run another dxdiag.
(Thanks again, @holger1405 .)
