Solution

This is a known issue that, although it is common on Mac machines using the Bootcamp's Windows 10 Partition, can also happen in Windows 10 machines. See the relevant sections below for the solution steps.
 

Mac Bootcamp Partition

The problem is originated because the computer IDs of all the Bootcamps' Partitions are by default set to 6PZC-LFP4-SCXY-DFB6, and, as the licensing of the NI software is now identity-based with every machine, that specific computer ID has been blocked.  

To fix this issue, contact NI Technical Support with the computer's MAC Address to create a new computer ID for the machine. Then, create new activation codes using the new Computer ID following the Getting 20 Digit Activation Codes for NI Software guide.

 

Standard Windows 10 PC

  • Reinstall the software to be activated.
  • In case the issue persists after the reinstall, follow the same steps to solve the issue in Bootcamp partition.
