# Step 3: Unpack the plugin files

Since the plugin files are package files, they must be unpacked.

1. Unzip the plugin file you would like to install. Inside is the packaged file.
2. Run the `install.bat` file to unpack the plugin file.

   The IZPak window appears.
3. Read the license agreement in the IZPack window.
   1. Select the **I accept the terms of this license agreement** check box
   2. Click **Next**.
4. In the **Select the installation path** text box, browse to or enter the directory where you created the `\pentaho\server\pentaho-server\pentaho-solutions\system` directory, and then click **Next**.

   A warning message appears informing you that the directory already exists.
5. Click **Yes**.

   Any existing files in the directory will be retained.
6. Click **Done** when the installation progress is complete.
