Issue Details

I am attempting to install software on my Real-Time Target, but it hangs at "Base.tar" and times out. How can I overcome this error?


  • Format the Real-Time Target and try to install software again.
  • Connect to the Real-Time target directly via Ethernet or USB.
  • This behavior is generally caused by firewalls, antivirus software, or other services blocking the transfer of necessary files for the Real-Time target software install. 
    • Ensure that any firewall (including network-based) or antivirus software on the computer grants access to National Instruments software.
    • If your computer has any services that could interfere with file transfers, consider disabling those services as a test while attempting to install software to the Real-Time target.
    • This can also be caused by a file transfer issue due to the size of the base.tar file that is sent via WebDAV. Increasing the WebDAV file transfer size in Windows could aid in this scenario.
    • Try installing software from another computer that is not on the same network, ensuring that corporate or network firewalls are not interfering with this install.
  • To address any potential issues in the software on your host, reinstall the software for your Real-Time target on the host computer.

Additional Information

If you attempt to install software with the Install (VI) in LabVIEW, this behavior may be presented as error -2147220324.
