DDJ rb Windows 7home not working

why application rekordbox so difficult when going in use 
I would like to say tired to Pioneer dj why create an application 
that is so difficult in the plug in the appliance itself, 
I've tried to install on laptops Windows 7 Home 
My spec Corei5 4gb ram 500GB hard drive, 
I've tried many the way he had described on the post that 
has been described tetapo still can not be, the case when 
audio in applications rekordbox transferred to the audio DDJ RB 
still can not always get an error, because when I clay from a 
previous post I have to go into the SOUND in the control panel,
 sound image that reads LINE no manager Sound, 
whether pioneer has a reliable technician in jakarta ??
