Error using loadlibrary - loaddefinedlibrary: Read TDMS-files

I'm trying to load a TDMS-file into Matlab (I use Matlab R2014a) I followed this instructions: http://digital.ni.com/public.nsf/allkb/A9094170BAC9A0EC862572E300352CBD

his error occurs:

>> examplePath = 'C:\test';

hfile = [examplePath '\nilibddc_m.h'];

loadlibrary([examplePath '\nilibddc'], hfile);

Error using loadlibrary (line 422)

There was an error loading the library "C:\test\nilibddc.dll"

Das angegebene Modul wurde nicht gefunden.

Caused by:

    Error using loaddefinedlibrary

    Das angegebene Modul wurde nicht gefunden.

Can anybody help me?

Sabine - looking at the link you provided (or the English equivalent) it seems that the code is from 2010 and only tested up to MATLAB R2008a. What version of MATLAB do you have? Did you copy the 32-bit h file and dll, or the 64-bit versions to your C:/test directory?
