  1. Extract files.
  2. Run setup.exe.
  3. Is this computer intended to be a client only or server also?
  4. If client only, then Sentinel Licensing and SQL Server is not needed, be sure to select the Client only option in the Vanguard installer.
  5. If server also, will it have local database or connect to the remote database?
  6. If remote database, be sure to select custom and no database option in the Vanguard installer.
