How to enable NI License Manager Logging

• My NI License Manager is crashing and I need to troubleshoot it.
• I need to get the logs from my client machine because NI Volume License Manager is not activating my network license correctly.

1. Open the command prompt.

• Hit Windows Key + R > type cmd > hit Enter
• You can also use Windows PowerShell instead.

2. Navigate to the Licensing Manager Installation Directory

cd "C:\Program Files (x86)\National Instruments\Shared\License Manager\"

3.  Enable Logging by running the command 

• In command prompt use: 

NILicensingCmd.exe -enablelogging

• In PowerShell use: 

& .\NILicensingCmd.exe -enablelogging

4. The log is writtten in the file C:\ProgramData\National Instruments\License Manager\Data\Licensing.log.

Additional Information

• The default logging time is 7 days. If you want a different logging time, you can specify it by adding the number of days behind -enablelogging, e.g. -enablelogging 1 would log only for 1 day.
• To disable logging, use the option -disablelogging.
• Once you've done this test, you should move the logfile to a different directory, so that you start with an empty log for next tests.
