Note: NI does not provide activation keys for third-party add-ons. It is the responsibility of the third-party add-on developer to handle all issues related to the activation of their product.
If you need to activate the Third-Party Software offline, you might try to use our Third-party activation code generation page. During the process, please make sure that the "User Code 1" and "User Code 2" were correctly copied. This code is usually 9 digits and it should be the same as the User Codes on the PC where LabVIEW is installed. You can verify your User Codes by opening LabVIEW >>Go to Help >> Click on Activate Add-ons >> Choose the software you would like to activate >> Select Use a Web browser on this or another computer to acquire an activation code.
