DreamBot Client Won't Open Solution

Recommended Posts

Hello Everyone,

This thread has been suggested by @Infidel , due to the high amount of people experiencing this problem when first starting their botting journey.

I've listed 2 methods you could attempt, so let's get started!

1) Client won't open when DBLauncher.jar is clicked.

This may be due to several reasons but most commonly it's because your computer may lack Java 8 OR It has it but your computer also has other versions installed on it and when you try to load any Java applications, the higher version (Which would be probably set to default) loads the JAR file instead of Java 8.

So.. what should you do? 🤔🤔🤔

First let's check the Java version installed and used on your Computer/PC! You can do that by:

1) Opening the Command Prompt (CMD) -> Search CMD in the start menu OR Terminal for Mac.

2) Type in 

java -version

and you'll be faced with the following details:


If the java version doesn't output "1.8" then you could be either of these situations:

1) You have Java 8 Installed but the system is using another version.

2) You do not have Java 8 Installed.

Before continuing if you are sure you do not have Java 8 installed/downloaded: click here to download JDK/JRE 8 . 

To check whether you have Java 8 Installed or not:


head over to your Java folder located in your Program Files / Program Files (64bit)


You'll see all Java versions that are installed on your PC.

Mac OS: (Paste this in Terminal)

which java

It'll output the current Java version installed.


Now we will set the Environmental Path (To tell your system to use Java 8 )


Get the Path To Your Java Installation:


To fetch the Java Path:  

Mac OS: (Terminal)

which java

Windows OS: (CMD)

where java

This gets the path of every Java Installation you have! Copy the Java 8 Path



Setting the Environmental Path: (Assigning Java 8 as the default Java version)

for Mac OS:

Run the following command in your Terminal: (Make sure to change the Java version "Orange number" to the version you found in your Java folder)

% /usr/libexec/java_home -v 1.8.0_73 --exec javac -version


for Windows:

Run the following command in your Command Prompt (CMD): (Change the path (blue text) to the path of your Java Installation)

setx -m JAVA_HOME "C:\ProgramFiles\Java\jdk1.8.0_XX"



Restart CMD/Terminal and type in

java -version

If it displays 1.8, then everything worked great!


If you guys have any questions, please do leave a comment and I'll answer them to the best of my knowledge!

Have a good one guys!

How are they unclear? Please point the "unclear" parts so I can modify them


Edit: I rewrote some of the text below to make it more clearer!
