I'm having trouble installing this as well. I'm trying to install using the newest (2.3) windows installer on a Windows 7 64-bit system that I recently reformatted no less than 2 days ago. (Yes, I have the current java.) Every time I try to run the .exe I am presented with the attached image. Also, I guess I have very limited knowledge of dos and/or command scripts, but am very computer literate and can follow instructions as long as it's not assumed I can just whiz around through dos.
Now, I know through the hundreds of message boards and forums I've been a part of that you will all scream for me to "SEARCH WTF SEARCH" etc. etc., but frankly it's the middle of mid terms and I have no time to search through 18 pages of web forum mumbo jumbo.
And finally, THANK YOU! Hope I don't come off like a jerk. Sincerely guys, thanks for the awesome tools.
