NI Software Does Not Open Because of Missing msvcp140.dll

Issue Details

• I can call LabVIEW code from TestStand when the LabVIEW Development Environment is installed.  However, if only the LabVIEW Run-Time Engine is installed, calling LabVIEW code with the RTE gives the missing DLL error.
• I uninstalled several software from my cDAQ controller and after trying to run LabVIEW it gave missing MSVCP140.dll error.
• I receive an error message detailing "the program can't start because msvcp140.dll is missing from your computer.” 

Solution

1. Issues related to corruption of msvcp.dll can usually be corrected by installing the Visual C++ Redistributable for Visual Studio 2015, which can be found here Visual C++ Redistributable.
2. If installing the redistributable itself doesn't work you can try installing the latest update to it found here Visual C++ Redistributable update.
   1. NOTE: When downloading the redistributable or redistributable updates, select the executable corresponding to the same bitness as your LabVIEW program, not your operating system.
      - vc_redist.x64.exe corresponds to 64-bit
      - vc_redist.x86.exe corresponds to 32-bit
      
3. A complete uninstall and reinstall of National Instruments software can fix potential software corruption.
4. Lastly a reimage procedure could be needed if no other option work. Although this is the most time consuming this could avoid error about other DLLs missing.
