Issue Details

  • I am trying to build a volume license installer for my volume license agreement (VLA) using the Create a Volume License Installer article. When I click Build, I get an error that says "An unexpected error occurred while building the Volume License Installer."  
  • I recently upgraded to VLM 3.2 and I am having problems building installer on the disk.
  • It has been running very slowly and the same error occurs every time.


  • This error occurs, or VLM Installer crashes, when there is not enough local disk space on the machine running VLM, not the machine where the installer is being built. To resolve this, increase the local disk space available.
  • This was an issue that was happening in versions of NI Volume License Manager (NI VLM) 3.2 and prior.  To resolve this error message, upgrade to the latest version of NI VLM
