Issue Details

  • I am trying to install LabVIEW NXG using NI Package Manager (NIPM) and receive an error saying: There was a problem executing your request.  Invalid checksum for the package and then points at a file path.  How can I get around this and install LabVIEW NXG successfully? 
  • During installation of LabVIEW NXG I get the following error:
Package signature validation failed for package 'ni-labview-nxg-2.0.0-analysis-advanced-bin'. Expected MD5 checksum '7d9726d8de6e612a74b98 6ac550f2dc' is different from actual checksum '5bd9422c4488cb52f9b10b4819b864ad' The package may be corrupted: C:\ProgramData\National Instruments\NI Package Manager\packages\ni=labview-nxg-2.0.0-advanced-bin_5.2.049154-0+f2_windows_x64.nipkg 
Please check your internet connection and try again.


  1. Check your internet connection. Refer to the Problem Updating Feeds When Installing Through NI Package Manager document for more information.
  2. Make sure you have the latest NI Package Manager release: Download NI Package Manager .
  3. 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 NXG, and you can then re-install that component. 
  4. Delete the package that's having the problem:
    1. Navigate to C:\ProgramData\National Instruments\NI Package Manager\Downloads 
    2. Search for the name of the package you are having the error. 
    3. Delete the package.
  5. Restart NI Package Manager and try installing LabVIEW NXG again
Note: The ProgramData folder in Windows is a hidden folder. Follow the next guide to show it: External Link: Show hidden files.

If you can download and install a different package from the NI Package Manager store, contact NI Support and reference this article.

Additional Information

This error message can be caused by internet connectivity issues. Try downloading another NI Package Manager package. If that package also fails, the problem is most likely caused by your internet connection.
