Minecraft Launcher doesn't open at all

Here is what happened.
First, I went to play Minecraft and it said there was a new update. So, I let it update. However, when I went back the next day to launch Minecraft, the launcher wouldn't open. I have already tried several things: Compatibility check, updating Java, deleting the .minecraft, and redownloading the Minecraft.exe file. Minecraft Launcher still won't start.

NOTE: No, there were no error messages of ANY kind. The launcher didn't even start, and nothing happened at all. Also, I tried to use Tekkit but that didn't work either.
IMPORTANT: I tried playing Minecraft in my browser, and it worked. This is definitely a Launcher error.

Please help me! I need my Minecraft!!!!!!
Thank You
