When starting Minecraft the system shows the Mojang masks and gets stuck.
When I use task manager and "kill" Minecraft / Java Plattform Binary, the main mask appears and asks in German for Apologies that Minecraft has crashed (see attached Screenshot 1).
Sometimes I was able to get to the mask, where I can chose singe or multi player.
Then I already tried to

• Start the game --> It gets stuck again, see Screenshot 2
• Change Language to German ..> When I choose language and push the mouse it gets stuck again. Same situation: I can kill with task managers and receive again the apology mask.

I tried it on- and offline. Attached you see two erro protocolls (screenshot 3 and 4) as I left game output on.

I read several forums. So I made a second profile and have changed the following setting of the java program file:
C:\Program Files (x86)\Minecraft\runtime\jre-x64\1.8.0_25\bin\java.exe
C:\Program Files (x86)\Minecraft\runtime\jre-x64\1.8.0_25\bin\javaw.exe

No difference.

I really dont know what else I can do and my little boy is asking everyday when I will fullfill my promise to install Minecraft. I hope you can help.
Thanks
