Solution

There is no single reason why this error could be happening. To resolve the issue, try the following these steps:

• Check your internet connection. Refer to the Problem Updating Feeds When Installing Through NI Package Manager document for more information.
  1. If you are installing from an offline installer, this may mean that it's corrupted:
  • Delete the downloaded file and re-download it and move it to the offline computer.
  • Try mounting the offline installer (ISO file) and extracting all the files before moving them into the offline computer. Note: Some encryption from external devices may corrupt the ISO file.
• Make sure you have the latest NI Package Manager release: Download NI Package Manager .
• Try uninstalling the specific component at the file path pointed out in the error message. In some cases, removing this component will allow you to install the software, and you can then re-install that component. 
• Delete the package that's having the problem by following the steps in this document.
• Restart NI Package Manager and try installing LabVIEW NXG  or the NI software you are using again.
• Download and install the offline installer for the software from NI's website
