Deactivate, Remove or Transfer License for NI Software

Updated Apr 10, 2019

Reported In

Software

  • NI License Manager

Operating System

  • Windows

Issue Details

  • I want to transfer my NI Software to another machine, laptop, or hard drive. How do I deactivate, remove, or disable my license for an NI product?
  • I'm wondering how/if it is possible to uninstall a license and move it to another computer.
  • Do I have to uninstall/unlicense my software from one computer before using it on another computer?
  • I will be reimaging my Windows machine and would like to make sure my license is not double-counted because it was activated on a previous image.
  • My computer crashed and I cannot access it. Do I need to deactivate the NI Software on it, before I install new software on a new computer?
  • I'd like to develop my software at my office computer as well as on the computer at the test site. Is that possible with a single-seat LabVIEW license? Also, how can I transfer the development system?

Solution

Depending on the license, you can install and activate LabVIEW on multiple machines. A single seat license allows you to activate LabVIEW on up to three machines (ex. work desktop, work laptop, and personal computer). For more information on the types of software licenses, refer to NI's software policies.

If you have activated the maximum number of computers permitted by a license, but you want to start using another computer, you can deactivate a current computer to then activate the new computer. You can deactivate products within NI License Manager 3.7 and later versions. The instructions to do so follow.
 

NI License Manager 4.0 and Later

  1. Open the NI License Manager utility, located at Start»Programs»National Instruments»NI License Manager.
  2. Go to the Local Licenses tab for local or disconnected licenses.
  3. Expand the software package you wish to deactivate.  The activated project should have a solid green icon next to it.
  4. Click to highlight the software that you would like to deactivate. After highlighting the software, the Deactivate icon should appear next to the Refresh button.
  5. Click Deactivate as shown in the image below.
 
 

NI License Manager 3.7

  1. Open the NI License Manager utility, located at Start»Programs»National Instruments»NI License Manager.
  2. Expand the software package you wish to deactivate. The activated product should have a solid green icon next to it.
  3. Right-click on the activated product that you want to deactivate and choose Deactivate.
  4. If you are sure you want to deactivate the product, select Yes.

This will revert the product to an unactivated state. To use the product again, you must first reactivate the product. 
 

NI License Manager earlier than 3.7

With NI License Manager versions earlier than 3.7, you must remove the license file manually. Steps to follow are:
  1. Close all National Instruments products.
  2. Open My Computer.
  3. Navigate to the License folder, located in the following directory: 
    • Windows XP - C:\Program Files\National Instruments\Shared\License Manager\Licenses.
    • Windows 7 - C:\ProgramData\National Instruments\License Manager\Licenses.
  4. Find and move the license file to your desktop. In order to find the right license file, the naming convention is <Application Name>_<Product Name>_PKG_<Version>.lc. For example, if you wanted to remove the LabVIEW Application Builder license file, you would need to remove LabVIEW_AppBuilder_PKG_090000.lc. Note that the file extension may be either .lic or .lc.
  5. Open NI License Manager and check to see if the product is still in the list.
  6. If the product is removed, delete the license file. Otherwise, move the license file back and repeat steps 4 and 5 to find the correct license file.

 

Additional Information

  • NI License Manager is installed automatically with any National Instruments software that requires a license to work. If you are installing licensed NI software, you do not need a separate installer for NI License Manager.  
  • You are not required to notify National Instruments when you deactivate a product. NI does not allow or disallow future activations dependent upon a previous deactivation. Common reasons for deactivation include moving the license to another computer and inadvertent activations. 
  • If the product is using a disconnected license generated by NI Volume License Manager, you can deactivate the license by right-clicking the product and select Uninstall License File. The caveat is that other products using the disconnected license will be deactivated as well. To fix this, you must generate a new disconnected license file from the Volume License Manager server.
  • If you recently inherited a single seat license from another employee that previously worked at your company, contact NI Support to determine if you can transfer the license's association from their ni.com account to your account.
