Seems like a subject of "Eclipse 3.2 Won't Start" would have been a better, more informative subject for this topic, don't you think. Might take some time and read
this for future posts.
As to your problem, I don't know. I downloaded and installed 3.2 in Windows XP no less than 15 minutes ago and it works just fine. Did a search on google for your problem and there seems to be quite a bit of useful information. You might check that out while you wait.
