Solution

Check that all files involved in the LabWindows/CVI project has been compiled for the specific operating system (e.g. Windows 7, Windows 10). Ensure as well that all driver software needed is installed and that the version of the software is compatible with the operating system. The compatibility information can be found in the software Readme.

If the above are true and you are still seeing the error message, try uninstalling all NI software, and reinstalling the newer versions you are trying to run the program off of.

Additional Information

This appears to occur when the LabWindows/CVI code used to build the LabWindows/CVI DLL involves libraries or DLLs that were compiled for an older Windows operating system like Windows XP.
