'Cannot load library d3dx9_41.dll'

This is an old DirectX 9 error. We have updated Biofield Viewer from DirectX 9 to DirectX 11 in version 4 onwards, and DirectX 12 from 4.1.
Email or Facebook message John Catchpole for the latest update.

If you wish to continue running an older version of our software built for DirectX 9:
'Cannot load library d3dx9_41.dll' means DirectX 9 we use isn't installed. The Biofield Viewer installer should install it, but in some instances like a Mac running Windows you may need to run the Microsoft web installer.
Go to and open the section 'Windows XP and Windows Server 2003' to reveal download links for the DirectX End-User Runtime.


Email with any installation questions.
