Windows IDE Does Not Start

Hi, This is my first time trying arduino. I can not start the IDE.
It termiates just after the splash screen. And I have no clue to follow.

OS: Windows 7 Pro x64 SP1 English.
Java: Version 7 Update 4 (build 1.7.0_04-b22)
IDE: 1.0.1 ( from

  1. I downloaded and unzipped the files into c:\ardunio
  2. I've installed the driver for ardunio uno r3
  3. I've clicked to run arduino.exe
  4. Splash screen appeared just to disapper after seconds. (No arduino process show up in task manager)

C:\arduino>arduino.exe --l4j-debug ( found this on the internet.)

Java is not being detected, it should say (ok) not (n/a) in the debug. Of course I suggest you to use my Installer :slight_smile:

Thank you. You are amazing!
