  • 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 the previous installation are still stored in the program and I want them gone so that I can create a new one. 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 when you launch Volume License Manager, it will load the startup screen as it has not been configured before.
