Before You Begin:

  • Ensure that you have installed the latest version of Microsoft Visual C++ 2010 Redistributable Package for your 64-bit platform and architecture.

The directories that contain the Tenable Network Monitor binaries must be writable only by special users like administrators to prevent other users from acquiring elevated privileges granted to Tenable Network Monitor.
