Windows DLLs "api-ms-win-core..." Not Found When Calling LabWindows/CVI DLL

Issue Details

When calling a compiled .dll file from TestStand or LabVIEW, I see the following error or something similar:

Solution

• Check that all files involved in the LabWindows/CVI project have been compiled for the specific operating system (e.g. Windows 7, Windows 10). If you have updated the OS of your system, NI recommends uninstalling NI software and reinstalling it. 
• Open LabWindows CVI as administator. This step should be tried even if you believe you have local admin privileges. If you are using CVI with another program, such as NI TestStand, try opening the other software environment as administrator as well. 
• Ensure 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 file.
• If your DLL references other DLLs, make sure they are placed inside the main DLL's directory.
• Try uninstalling all NI software, and reinstalling the newer versions you are trying to run the program off of.
