# Specifying another JVM to launch Talend Studio

If you have more than one JVM installation on your machine, you can specify which one to use to launch Talend Studio for a particular purpose.

## Before you begin

Download and install the JDK of the new Java version that you want to use.

## Procedure

1. Go to the root of your Talend Studio installation directory and open the .ini file with a text editor.

   For Windows, the file name is Talend-Studio-win-x86\_64.ini.
2. Edit or add the -vm option so it points to the Java executable of the JVM version with which you want to launch Talend Studio.

   Make sure to follow these rules:
   * The -vm option and its value must be on separate lines.
   * The -vm option must be defined before the -vmargs option, because everything after -vmargs is passed directly to the JVM.
   ### Example

   For example:
   ```
   -vm
   C:\<JDK_HOME>\bin\javaw.exe
   ```

   or
   ```
   -vm
   C:\Program Files\Java\<JDK_HOME>\bin
   ```

   or
   ```
   -vm
   C:\<JDK_HOME>\bin\server\jvm.dll
   ```
3. If you installed Talend Studio using an Installer, the shortcut that was created for you is still using the previous Java version. Either change the value of the -vm option in the shortcut properties, or delete the shortcut and recreate it manually.

## Results

Next time you launch Talend Studio, it is using the new Java version. For more information, see [Launching Talend Studio](https://help.qlik.com/talend/en-US/studio-user-guide/8.0/launching-talend-studio).

Then, if you want to check which JVM version Talend Studio is using, open the latest logs located in &lt;workspace&gt;/.metadata/.log. They will show you the Java version used. For example:

```
!SESSION <timestamp> -----------------------------------------------
...
java.version=17.0.10
java.vendor=Azul Systems, Inc. 
```
