Problems with Arduino 1.0

Hello, I have dowloaded an unzipped Arduino 1.0, but when I try to open it the star image shows up and two processes appear in the tasks manager, then that processes close and the image disappear, but nothing happens. I have Windows XP x32

Really appreciate some help.

I have also experienced this with other Arduino versions but never figured out the exact cause. Does this occur with any other version (like 022)? I assume you have tried restarting your computer. You may have a JAVA installation problem. Try reinstalling JAVA.
