Download the newest version of Java+JDK.
HMM, tried installing that, still doesnt work
1. i have 32 bit.
2. ive been saving it the entire time
1. Download Rsbuddy to desktop
2. Rename Rsbuddy to "bot"
3. Open notepad and copy and paste this into it
@echo off
java -jar bot.jar
4. Save the notepad document as "bot.bat" on the desktop
5. Run the Bot.bat file and it will open rsbuddy
I had the same problem but got it fixed.
maybe post a video or get a screenshot of what the CMD says
I always have problems with java and the cmd closing, its usually means that something is missing or the code was wrong.
I had the same problem (WIN7 32BIT)
i deleted everything (all rsbuddy files/java files/jdk anything that can affect it)
Re-download see if that helps out at all.
also, I know you already you said this but if you do what i mentioned above make sure the path is still correct as in the earlier post says (not me)
