Even not knowing dutch, I'll try do add some informations...
CVI can be installed with different "compatibility modes": Borland and Microsoft. The compatibility mode affects the way CVI interacts with DLL and other libraries and must match the one of the libraries used in the project.
You find which compatibility mode your installation of CVI is set by looking at Option >> Build options menu in project window. At present, it seems that CVI installation is now different from the libraries installed with NI-DAQ. It may happen if the copatibility mode was changed after the installation of NI-DAQ, as explained in this
Knowledge base entry.
Now you have two choices:
1. Reinstall NI-DAQ as explained in the document liked above
2. Change compayibility mode in CVI by running the CVI installation program and choosing the appropriate option (until version 6) or inside Options >> Build options panel starting from CVI 7
The first option seems the safest if you have several code developed and functioning in your environment (i.e. the amount of libraries actually installed in the computer CVI is installed on). If you run the second you may get this same error while loading other libraries or instrument you are not able to update.
