Can't start appium inspector and arc command from console

hej everybody. I'm new in appium, so excuse for obvious questions. I need start to test with Android device/emulator using appium. I have next configuration:

1. 
   

   AS 1.1.0

   
   


2. 
   

   Appium.app 1.3.5

   
   


3. all necessary components from official site


4. Genymotion 2.3.1

my Android settings

my General settings

when I check settings with launching doctor all fine

Launch server

But when I launch Inspector I have an error

run app with arc

I have the same error when launching arc from terminal like from this

Can you explain me how to correctly use appium? How to run tests and where they should be written? Thanks a lot for any information.
