Deactivating a Product
To deactivate a product and return the product to the state it was in before you activated it, right-click the product in the NI License Manager tree and select Deactivate. If the product was in evaluation mode before you activated it, the properties of the evaluation mode may not be restored.
Reactivating a Deactivated Product
You can reactivate a deactivated product using the NI Activation Wizard. If you saved the activation code from a previous activation for this computer, select Apply one or more 20-character activation codes previously acquired for this computer and follow the prompts. Otherwise, select one of the other two options and follow the NI Activation Wizard prompts.
