After some use of the Arduino IDE I found it annoying that it wasn't installable. While it is useful to have a non-installing program in an environment with strict user restrictions (Like a school or at work) at home it is nice just to have Arduino automatically have registry settings for the opening of *.ino files and be in the start menu. So I created an Installer for the Arduino IDE with Inno Setup. This is downloadable from my google drive.
CURRENTLY ARDUINO 1.0.1
