hi 
when i downloaded forge 1.7.2 forge 
and installed USING THE INSTALLER 
and latest version ( 10.12.0.999 ) 
i start the official minecraft launcher  
i select the Forge profile and hit Play 
it loads then the green bar go away and nothing happens 
  
i know you want the [ForgeModLoader-client-0.log] but because the game not starting its not being created  
but you can still have the minecraft report  
  
this always happens i guess its about a file called launchwrapper-1.x.jar failing to download i usually download it manually but this version [ 1.9 ] i just couldn't find a download link 
can someone help me or give me a link to that file
