Issue Details

The Licensing Wizard shows that there was a problem accessing NI's activation server, saying cannot connect to I have tried opening up LabVIEW and I get the same error. 

I have successfully used the serial number to activate LabVIEW in the past. However, I get the message above from the Licensing Wizard when I either:
  • Activate the software on a different PC
  • Activate different version of LabVIEW on the same PC, after installing previous versions
  • Activate a different software


Please follow these troubleshooting steps:
  1. Activate the software using License Manager . Verify and use you serial number and check to see if the activation works successfully. 
  2. If step 1 was not successful, start with a repair of all the software that you are trying to activate. After you repair all the software that you are having problems with you can try to activate the software again.
  3. If step 2 was not successful, perform a force reinstall of the software that you are trying to activate
  4. If all other steps fail, please contact National Instruments Technical Support.

NI Package Manager does not give the option to repair, so if using NI Package Manager you will have to uninstall and reinstall
