You must have Java installed to run the client. I believe RSBots.Net client comes with a .Jar file. You must double click the client and it will begin to load. Once it loads reply back on the forums and I will help you with setting up your bot.
You do need java downloaded like the guy above says. You can download the client on rs or you can go to the oracal to download it. Here is a link http://java.com/en/. After downloading the java go to the rsbots.net and download to a folder. You will have to unzip the folder you downloaded into another sepperate folder. Click on the folder that you unzipped to and click on instal set it up and your good to go. Add your auth code from there. If you have any questions add my msn and i canhelp you through the instal procces.
Thanks everyone, i had a friend set it up for me though. Bot is working good! Just wondering if anyone knows if these bots are good for money/exp: AutoFlaxer, AutoPlanker AutoSmither and AutoSmelter.
