Arduino Studio 1.6.3 with Xadow?

[avoid]

i have tried it with the new 1.6.4 (make a fresh install, add the files from github) and then i load the UserLed example.
now i get this:

C:\Program Files (x86)\Arduino\hardware\arduino\avr\cores\arduino\USBCore.cpp:25:22: fatal error: Platform.h: No such file or directory
#include “Platform.h”
compilation terminated.
Fehler beim Kompilieren.

Sorry, now it works.
I had not noticed two things.

1. To utilize the version 1.6.x should I only the two files for 1.6.3 are not using the other.
2. I have to adjust not only the Board (in my case Xadow) but also the programmer to “USBtinyISP”.
