Issue Details

I receive the following error after entering the serial number while installing NI Software. How can I fix this?

An Error Occurred on the Server. Would you like to try again?


This error generally occurs because a firewall blocks the connection to the server for serial number authentication. It will be necessary to first make sure that you have the correct software versioning downloaded for your product. 

If You are Installing on a Personal Computer:
Temporarily disable the Windows firewall and any spyware or malware protection. 

If it is a Company Computer:
  • Download the correct version of the software from the NI Download Page.
  • Select the Software tab and navigate to the NI LabVIEW subsection and select Download.
  • Once the software download completes, try again to enter your serial number through NI License Manager. 

To do this, you can navigate to the appropriate License for your product. Then enter the serial number for your product. If you need assistance finding your serial number, please reference the article here.

If the software does not accept the serial number or the error persists, contact NI support .
