   If you can't download that server.pem, the common causes are that your server isn't running or there are firewalls in the way.
  
positive.code: Linux: Stop the daemon version of the service and run it in verbose mode:
  ----
  $ sudo service grr stop
  $ sudo /usr/sbin/grrd --config=/usr/lib/grr/grr_3.0.7.1_amd64/grrd.yaml --verbose
  ----
  
  OS X: Unload the service and run it in verbose mode:
  ----
  $ sudo launchctl unload /Library/LaunchDaemons/com.google.code.grr.plist
  $ sudo /usr/local/lib/grr_3.0.7.1_amd64/grrd --config=/usr/local/lib/grr_3.0.7.1_amd64/grrd.yaml --verbose

  Windows: The normal installer isn't a terminal app, so you don't get any output if you run it interactively. 
  
  - Install the debug ``dbg_GRR_3.0.7.1_(amd64|i386).exe`` version to make it a terminal app.
  - Stop the ``GRR Monitor`` service in task manager
  
  Then run in a terminal as Administrator
  ----
  cd C:\Windows\System32\GRR\3.0.7.1\
  GRR.exe --config=GRR.exe.yaml --verbose
  ----
  
  
negative.code: 
  You should have something like:
  
   - ``C:\Windows\System32\GRR\3.1.0.2\GRR.exe`` on windows;
   - ``/usr/lib/grr/grr_3.1.0.2_amd64/grrd`` on linux; and
   - ``/usr/local/lib/grr_3.1.0.2_amd64/grrd`` on OSX
   
  with variations based on the GRR version and architecture you installed (32bit is i386). If you didn't get this far, then there is a problem with your installer binary.
