Colored Screen - Pi dont boot

Hi,
i have a raspberry pi 2
i flash the micro sd card with the get-rasplex-win7-32.1.0.1.exe but when i start my pi, just a colored screen appears and he wont boot… i try the same thing with the win32disk imager, but same problem :frowning: if i flash raspbian onto the sd card, raspbian boot without any problems. what do i wrong ?

sorry my failure its a pi b+ not a pi2 :frowning: thread can be closed
