Arduino-0018: No arduino.exe

I've been up and running with Arduino-0012 on Win Vista and Atmega168. I couldn't get the interpreter/compiler to recognize analogReference(EXTERNAL); or analogReference(DEFAULT); so I decided to upgrade to Arduino-0018. Just downloaded and unpacked the .zip an hour ago (11 July 2010, 19:26 USA PDT). There is no arduino.exe in the arduino-0018 directory. How do I launch?

Well something must have gone wrong with the unzipping. Here are my contents:

Huh. I guess I should re-download and re-extract. But since I just got the old arduino-0012 analogReference() to work, I think I'll just stick with that.

Thanks for the message, retrolefty.
