Solution
Activation rules for multiple computers varies based on the type of
National Instruments 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: A user may install and activate the National Instruments Software on up to three (3) computers, each by following the traditional installation and activation process. You can run LabVIEW or LabWindows/CVI on only one of these computers at a time.
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
