Hi Andreas,
Make sure that you version of LabVIEW is supported by the version of NI-DNET. Here is a knowledge base article that shows you all supported combinations:
KB: What is the Latest Version of NI-DNET That Supports My Version of LabVIEW or LabWindows/CVI?If you have a match (i.e. your version of NI-DNET does have support and example files for your version of LabVIEW), make sure that you install LabVIEW
before you install NI-DNET, and the NI-DNET installer will automatically install the support files (and examples) for you. If you install NI-DNET
first, you need to make sure to manually select the LabVIEW Support feature for your specific LabVIEW version as well as the 'Examples' feature.
