Do not let me start Minecraft (For new launcher)

When I start the launcher and download the new version, at the time of loading the launcher, it appeared that I did not respond.
Minutes later I wanted to open the launcher and I do not leave, I do not see any message, or something that is wrong, it just does not start.

Reinstall minecraft, Java and restart my pc, but the launcher still does not respond.
I hope you can respond to me as soon as possible.

I do not speak English, I'm with a translator, I hope you can help me.
