NI MAX Error: Execution of External Command, Script or Application Failed

Issue Details

You are seeing  Execution of External Command, Script or Application Failed error  on NI Measurement & Automation Explorer (NI MAX)  while you're trying to:

• Upgrade the software or driver versions on your Real-Time (RT) Target
• Install new software on your RT Target

Solution

•  Power cycle the RT Target or reset your device
•  Verify that firewall allows the usage of the following UDP/TCP ports: 44515, 44525, 44516
• Verify that your Antivirus is not blocking the download of the software, if possible turn it off
• Connect the device in a different way (switching Ethernet to USB if supported, or using a new Ethernet/USB cable) 
• If you have an identical RT device that is working correctly, you can replicate its image and use it to deploy your RT Target which is not working.
• If you have followed all the procedures and the problem still persists, try to connect your RT Target to another PC, and try to install the software again.
