A strange problem

[ComBlockWither]

When I run Forge installer (latest or recommended), select "Install client", and press "OK", installer began downloading a files (it's no problem). But at 75% they... don't close (javaw.exe still running), and stop work. Log are here: http://pastebin.com/RvVAXmFK

And, Java: 8; Minecraft: 1.7.10; Windows 7.

 

If you can tell me, how to load photos, tell. I will show you a screenshot.

Your paste is private, we can't read it.

 

Use an image hosting site like Imgur to host screenshots and post links here. I don't think screenshots are necessary for this problem, though.

Ok. My paste now not private. And

is here.
