6.5.2 Automatic Upgrade
Microchip Studio will automatically upgrade the tool's firmware when needed. A potential firmware upgrade is triggered once you start using a tool. Examples: The first time you launch a debug session or the first time you select the tool in the Device Programming dialog.
If the user chooses not to upgrade, Microchip Studio cannot use the tool.
You can also check for firmware upgrades using the Available Tools view (View → Available Microchip Tools). Right click on a tool and select Upgrade.
For a description of how to do a manual upgrade, downgrade, and upgrade with a custom firmware image, see Manual Upgrade.
