# Manage licenses using the PDI client

Follow the procedure below to install the licenses using the PDI client (also called Spoon).

1. Copy your license files to a convenient location.
2. Start the PDI client. See the **Pentaho Data Integration** document for more information on the PDI client

   If no valid license for the PDI client exists, the Pentaho License Manager dialog box appears. You must enter licenses to proceed.
3. From within the Pentaho License Manager, click the Add button (**+**).
4. Browse to the license file that you want to update, then select or multi-select the license file(s) (`.lic`) you want to install.

   A green check appears in the Status column to indicate that the license file (as displayed in the Product Name column) is correctly installed. The dialog box also provides the version, and installation and expiration dates of the license.
5. Repeat the previous step until all needed licenses are installed.
6. Click **Close** to close the dialog box.

   **Note:** To remove unwanted license files, select the files you want to remove then click the Delete button (**X**). When prompted, click **Yes** to delete the license.
