vizinput module missing

[whaleeee]

Hello,

I am trying to use some functions that should be included in the vizinput module. However, when I type 'import vizinput', I get this error:

import vizinput
Traceback (most recent call last):
  File "<string>", line 2, in <module>
ImportError: DLL load failed: The specified module could not be found.

I've installed Vizard on two separate computers and they both give the same error. I am using Vizard 4.0 Evaluation version on WinXP and Win7 (x64). Google searches have not revealed where to download the module or how to fix this problem. Can anyone point me in the right direction?
