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 as well and that the version of the software is totally compatible with the operating system.

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.
