You have to right click on the installer and run it in XP SP2 compatability mode as well as running it as Administrator.

If you need step by step instructions, let me know. I've been running it on Vista x64 for about 9mos now.

Depending on your Video Card, you're also going to run into driver issues between Vista x64 and Java/OpenGL causing the video driver to periodically stop responding.

Main cause is that there are no x64 Java drivers/software yet.

didnt work. Still giving me the same error. And i am positive I did it right,. Ive re-downloaded the installer at least 10 times.

I guess I just dont get to play online, lol. My infamous luck at work. Big surprise there.
