thinkorswim requires Zulu OpenJDK 11 to run; general installation instructions can be found on the Zulu website.

Once Zulu OpenJDK 11 is installed, ensure it is set as the default Java VM using the steps specific to your Linux Distribution. After ensuring Zulu OpenJDK 11 is the default with the "java –version" command in a shell/terminal, continue with the installation instructions below:

1. Click "Install thinkorswim" below to download the thinkorswim installer to a directory on your PC.
    
2. After downloading, open a shell and CD to the directory where you downloaded the installer.
    
3. At the prompt, type: sh ./thinkorswim_installer.sh

Note: For clients intending to run thinkorswim on Linux, Solaris, or other Unix variants, manual updates and tuning may be required. We have no official support for configuring these operating systems.
 

For Unix or Unix-like operating systems:

1. Ensure that Java 11 (Azul's Zulu OpenJDK 11 is preferable) is installed and accessible, then from your shell of choice, type: java -jar launcher.jar
    
2. If that does not work, try: java -classpath [path to] classes.zip:launcher.jar install
    
3. If that does not work either, on sh-like shells, try: cd [to directory where launcher.jar is located] CLASSPATH=launcher.jar export CLASSPATH java install
    
4. Or for csh-like shells: try: cd [to directory where launcher.jar is located] setenv CLASSPATH launcher.jar java install
    

Instructions for other platforms:

1. Be sure you have Java 11 installed (Azul's Zulu OpenJDK 11 is preferable). You can download Java from Azul's site.
    
2. In a console window, change to the directory where you downloaded launcher.jar to before running the installer.
    
3. Your operating system may invoke Java in a different way. To start the installer, add launcher.jar to your CLASSPATH, then start the main class of the installer named install.

Note: For clients intending to run thinkorswim on Linux, Solaris or other Unix variants, manual updates and tuning may be required. We have no official support for configuring these operating systems.
