+## Multiple License Keys Generation
+
+In v31.1.17 or later, if you have purchased multiple editions or SDKs separately and are using them in a single application, you must generate and use multiple license keys.
+
+## When this is required
+
+This applies when your application uses components from more than one edition or SDK, such as:
+
+- UI Edition and PDF Viewer SDK
+- Document Editor SDK and UI components
+
+## How to Generate Multiple License Keys
+
+You must generate license keys individually for each purchased edition or SDK.
+
+- Repeat the license generation steps for each edition
+- Each selection generates a separate license key
