DirectX 10+ vs. DirectX 9.0c - Windows 10/8/7/Vista Considerations

DirectX 10+ vs DirectX 9.0c
DirectX 10+ (ie DirectX 10, 11, 12, etc. ) is NOT a later version of DirectX 9.0c . These DirectX versions are designed to co-exist on the same computer. The bottom line is that even if you know you have DirectX 10 or later on your computer, it does not mean that you have DirectX 9.0c installed. DO NOT uninstall DirectX 10+ if it is already installed. Simply install DirectX 9.0c.

Detail for those who are interested: Windows® 10/8/7/Vista computers come with DirectX 10+ installed and not 9.0c. DirectX 10+ cannot be installed on Windows XP. DirectX-10+ and DirectX 9.0c (a.k.a. DirectX 9.0Ex) are two distinctly different technologies. Microsoft also refers to DirectX-10+ as Microsoft XNA technology. Yes, it is a confusion of branding. Microsoft admits using the name DirectX 10+ for XNA is "misleading" for customers. If you run the DirectX Diagnostic Tool on Windows® 10/8/7/Vista , it will show the Version of DirectX 10+, not DirectX 9.0c. So it can be very confusing.
