I recently installed JDK to my computer. I have several questions below, I would greatly appreciate any answers and feedback. Thank you!

In my Java file it contains Jre7 (previous java) and Jdk1.7.0_17 (new java). Path: C:\Program Files\Java
Inside JDK there is a jre file: C:\Program Files\Java\jdk1.7.0_17\jre\bin

Problem 1: Everytime I click on Minecraft.exe, nothing happens. I have tried to reinstall it. I am guessing that my computer is running off the wrong java. How do I switch the java path for my computer?

Question 1: Should I delete Jre7? When I remove the file, everything that requires java comes up with this error: The registry refers to a nonexistent Java Runtime Enviroment installation or the runtime is corrupted. The system cannot find the path specified.

Question 2: Why is java not working at its current state with JRE and JDK?

Question 3: Why is there java files in Program Files and Program Files (x86)?

I am currently running off a .bat file to start my Minecraft.exe. The path is:

@ECHO OFF
SET BINDIR=%~dp0
CD /D "%BINDIR%"
"C:\Program Files\Java\jdk1.7.0_17\jre\bin\java.exe" -Xincgc -Xmx1024m -jar "Minecraft Client\Minecraft.exe"
PAUSE

don't use the bat and try it, adding more RAM to minecraft will help nothing unless you're running insanely large mod packs

I do need the JDK. Should I just uninstall all the java and redownload just the JDK?
