wine users - Apr 2010 - winetricks Directx9: Unsupported style(s) 0x144

I'm trying to install Tropico 3 and AppDB suggests that I install directx9.
So I type:

Code:
winetricks directx9

and after a short while it comes to this:

Executing wine c:\winetrickstmp/DXSETUP.exe
err:setupapi:do_file_copyW Unsupported style(s) 0x144
err:setupapi:do_file_copyW Unsupported style(s) 0x144

Then this is repeated like 40 times. I suspect that directx9 isn't installed
here because the game barely runs on low settings.

How do I get directx installed correctly?

The only part we really use from native directx9 are d3dx9_* helper dlls. The
core of DirectX9 namely d3d9.dll is provided by Wine and it makes Direct3D9 to
OpenGL. If performance is low it is likely because you are using slow video
drivers or a slow videocard OR your 32-bit opengl drivers have not been
installed correctly.
