Activating LabVIEW or LabWindows/CVI License on Multiple Computers

Issue Details

• I have a LabVIEW or LabWindows/CVI development license and I want to install a copy on both my PC and personal laptop. Is there a limit to how many computers I can activate LabVIEW or LabWindows/CVI on?
• I installed LabVIEW or LabWindows/CVI on one computer and now want to move it to another machine. Is this possible?
• Can I activate a full version of LabVIEW or LabWindows/CVI on my deployment machine if I don't develop on it regularly?
• Can I run LabVIEW or LabWindows/CVI on two computers simultaneously using the same LabVIEW or LabWindows/CVI license?

Solution

Activation rules for multiple computers vary based on the type of NI Software License Agreement you or your company has. There are two main categories of license agreements: single-seat license and volume license agreement (VLA).

If you are not sure which type of licensing agreement you have, open NI License Manager and check whether your LabVIEW or LabWindows/CVI license shows up under the Local Licenses tab (single-seat) or the Network Licenses tab (VLA). Your software administrator can also provide this information.


 

Single-Seat License

LabVIEW  8.1 and LabWindows/CVI  8.1 to Present:
For Named User License, a user may install and activate the NI Software on up to three (3) computers, each by following the traditional installation and activation process. But, you can run LabVIEW or LabWindows/CVI on only one of these computers at a time.

For Computer-Based License, if multiple user use one license, only one PC can be installed. If you plan to use it for multiple people and install it on multiple machines, you need to purchase a new license and activate it.

LabVIEW 8.0 and LabWindows/CVI  8.0 and Previous: You can install the software on another machine, but you first must uninstall the software from the old machine. When you install on the new machine, simply follow the same activation process that you completed the first time you installed. Remember to follow the software licensing agreement by having only one active copy of your software installed at a time.

Note: If you need to use LabVIEW or LabWindows/CVI on a fourth machine with a single seat licence, you must first deactivate the software from one of the three other machines. Once the software is installed on the fourth machine, you can follow the same activation procedure that was used for previous activations.
 

Volume License Agreement

You may activate LabVIEW or LabWindows/CVI on multiple computers according to the license option outlined in your unique licensing agreement. For more general information on licensing, please refer to Understanding NI Software Policies.
 

Additional Information

Home Usage Exception: If you are a business or other entity using a Named-User licensing option, or if you are the primary user of the machine on which a Computer-Based licensing option is used, you may also install and use LabVIEW or LabWindows/CVI on one (1) home computer, provided that the use of the software on such a home computer is limited to work performed in the scope of and complies with all terms and conditions of your licensing agreement.

Note that this information applies similarly to single-seat and volume licenses for other NI application software, like FlexLogger.
