Microsoft DirectX® issues

Project Viewer must be installed onto a computer with a graphics card that is capable of supporting Microsoft DirectX 10 or greater and on which the DirectX End-User Runtimes are installed. If you install Project Viewer onto a computer that does not have the DirectX End-User Runtimes installed, a warning appears when you attempt to display the IFC Model pane.

To determine the maximum version of DirectX that a computer’s graphics card can support:

1. Launch the DirectX Diagnostic Tool by running dxdiag from the Windows® Start menu or from the Search charm in the Windows 8 Charms bar.
2. When the DirectX Diagnostic Tool appears, click the Display tab. The DDI Version field (the Feature Levels field in the case of Windows 8) indicates the maximum version of DirectX that the graphics card can support.

You can download and install the required DirectX End-User Runtimes from the following location:
