# ViDi Tool Editor

For deployed applications, if you need to retrain tools, you can create a Page with a ViDi Tool Editor element. This element replicates the ViDi Tool GUI, and offers the same functionality that exists while in Program Mode, which allows operators to retrain tools from an HMI.

Note:

- The use of the ViDi Tool Editor requires a runtime plus training license. Refer to the Cognex ViDi Licenses topic for more information.
- If you have multiple ViDi Suite Sub Task blocks in your project, and you only have a runtime license for your deployed application, each ViDi Suite Sub Task block must have the Deploy Training Workspace parameter set to False. If one of the ViDi Suite Sub Task block's Deploy Training Workspace parameter is set to True, the deployed application will attempt to create the components for a train license, and then fail when that license type is not available.
