  • Volume License Manager

I want to remove all current license servers from my Volume License Manager. I have reinstalled the VLM but my databases from before are still stored in the program and I want them gone so that I can create new ones. How can I force a total reset of the Volume License Manager?

​Go to the folder C:\ProgramData\National Instruments\Volume License Manager on your computer. Keep in mind that ProgramData is a hidden folder. 

Delete the following three files:

  • nilm.opt
  • nivlm.dat
  • nivlm.lic

    Next time you start Volume License Manager, it will load the startup screen as if it never had any settings previously.
