    Additional Information

    • A Technical Support Engineer will typically respond to your release code request within 12 business hours, barring holidays. Navigate to the NI Product Activation webpage below to activate current NI Electronics Workbench software.
    • If you are not sure what the Signature Code is, please launch the application. On the initial screen (where you get prompted to type in a release code) you will see that the Signature Code is displayed. It is important to give the correct Signature Code in order to get the correct Release Code.
    • If you are re-installing the software, and you get the same Signature Code as before, you are able to use the same Release Code that you were previously using. You do not need to get a new one.

    Multisim, Ultiboard and the Multisim MCU Module version 10 and higher are now using NI License Manager. Follow Activating National Instruments Software Products for these versions.
