Hi to all
I am new to Arduino. Most of my life I have worked with hardware R&D. I have decided to get into some software, I was told that Arduino Uno was the easiest way. I downloaded the Arduino software, installed it tried to run it and hit a wall. I got a dialog box telling me I needed Java 1.5.0 or better. After several attempts I got a version 10 and now I get a dialog box that is headed 'Java virtual machine launcher' with the message 'Could not find the main class: Processing.app.base. Program will exit.' This all confusing to me as I have absolutely no knowledge of Java and how it is essential to Arduino.
Can anybody help please?

What OS do you use?
And you really shouldn't post email addresses.
Hi
Thanks for the reply. I am using XP Pro.
Thanks for the heads up about the email address
It's a little odd that you should get errors regarding an outdated java version, as on winblows java is part of the IDE download file.
Back again.
You seem to know something about these programs/languages, and it confuses you, imagine how confused I am knowing absolutely nothing about Arduino or Java and the problem lands in my lap.
I have re-installed everything, and I have looked/am looking on the internet but I can't find a solution. there seems to be a similar problem for people who build ropbots but the solutions given for thier problem relates to the programming of robots and I don't know how the translate that solution to solve my problem.

p.s. 'winblows'?
'winblows', 'windoze' jocular for micro$oft windows. Mostly fed by bad experience (blue-screen, registry-rot...).
The 1.0 IDE download for winblows comes with this java version:
java version "1.6.0_16"
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) Client VM (build 14.2-b01, mixed mode)
And be sure to have enough RAM (it runs fine in a virtual machine with 768MB), inspect anti-virus software for possible interference, check the .zip file for corruption, unpack with all path information...
Hi Madworm and thank you
You nailed it. Because I was downloading this and that for Arduino, I was trying to get it to run on my small network that was attached to the Net. I appears that the security sofware was doing nasty things as the download came in.
I went to another installation and downloaded everthing to a USB stick then installed it on an independant network and all is worrking, as soon as I put it on the original network it went nuts until I took out the anti-malware then it worked OK on that network. so it looks like the add ons were the culprit in this case but I have not had any problems with them in the past.
So thanks again
Bill
