Temporary License Error When Configuring Hardware in MAX

Updated Sep 27, 2019

Software

  • Measurement & Automation Explorer (MAX)
  • NI License Manager

Issue Details

I am using Measurement & Automation Explorer (MAX) to configure my data acquisition hardware, and MAX is working correctly. However, sometimes a dialog box alerts me that "A temporary license has been granted, based on a change in hardware on this computer...". If I use the NI License Manager to check my license status, everything seems to be working correctly. Can I prevent this dialog box from appearing?

Solution

Windows XP
Go to your <Program Files>\National Instruments\Shared\License Manager\Licenses\ directory and delete all the license files with TmpEthernet in the name. Do not delete any other license files.

Windows 7/8/10
Go to your <ProgramData>\National Instruments\License Manager\Licenses\ directory and delete all the license files with TmpEthernet in the name. Do not delete any other license files.

 

Additional Information

This dialog box appears because a temporary license file has been granted to allow you to use DAQ Assistant and the temporary license is taking precedence over the license that is permanent. DAQ Assistant is used to help configure your DAQ devices with MAX and other National Instruments software products. To prevent this dialog box from appearing, you can remove the temporary license so that the permanent license can be found.
