You need to have the correct version of DirectX 9.0c installed in addition to DirectX11. Follow the instructions in this post:

Look for the DirectX Web Installer link in that post - under the heading
DirectX Details
[Aside: Don't be misled by the following statement in that post:
Quote: "If you have the latest DirectX installed, you won't have any problems with earlier updates of DBPro if you choose to run them."
as I think that is referring to the latest version of DirectX 9.0c not DirectX in general.]
Post back if you have further problems.
Many of us here install DBPro to a folder in My Documents rather than Program Files as that sometimes causes problems with newer versions of Windows. But try the DX9 Web Installer first.
