To run the administration tools, the directories with .exe and .dll files must be included in the path. You must add one of the c:\sa16\Bin32 or c:\sa16\Bin64 directories to the system path.

On Windows, the system path is stored in the following registry key:

HKEY_LOCAL_MACHINE\
  SYSTEM\
    CurrentControlSet\
      Control\
        Session Manager\
          Environment\
            Path
