red alert3 d3dx9_35.dll missing

Trying to run Red Alert 3, keep getting an Invalid Licence, d3dx9_35.dll missing. Running Windows 10 (which I hear has issues with trying to get dx9 working properly sometimes.
I have tried installing DirectX from the Windows site and from the RA3 folder after it downloaded. No luck. I can run C&C 3 (after installing dx from it's folder) so I'm certain I do have d3dx9_35.dll, since I noticed it get installed while running DX installer from C&C3 folder.

Also tried uninstalling and reinstalling RA3. Still no joy.
