Because available items are often controlled through your Silicon Labs account, it is recommended that you be logged in while using the Installation Manager. Install by connecting device(s) and Install by technology type are both described in Install SSv5 and Software. This section describes the Manage installed packages functionality.

Click Manage installed packages to open a tabbed interface where you can install and uninstall a variety of SSv5 components. Note that you can have more than one instance of some items, such as SDKs. You can use the Installation Manager to install additional instances as well as updates.

The interface opens on the Product Updates tab. Updates are grouped by type. If Product Updates are available these typically must be installed before you can install a new SDK.

After you install or uninstall items, for example as a result of an update or because you want to manage your SDK installations, SSv5 determines if a restart is required.

About Update Frequency#

By default, SSv5 checks for updates when you first open it. You can manage update frequency through Preferences > Install/Update > Automatic Updates.

launcher update frequencylauncher update frequency

  • Automatically find new updates and notify me (default: On): When selected, SSv5 automatically searches for update, as defined by the update schedule.

  • Update schedule (default: On startup): Look for updates on each startup, or once a day or some day a week, at a predefined time.

  • Download options (default: Search and Notify): Choose if SSv5 will search for updates and notify you of them once they are available or automatically download new updates and ask you to install them.

  • When updates are found (default: Once): Choose to be notified about new updates only once, or to receive reminders until the updates are installed.

If you have turned automatic updates off, you can check for updates by clicking Install on the toolbar, then Manage Installed Packages, and then Check for Updates on the Product Updates tab.


The Preferences button is a shortcut to the Windows > Preferences dialog (App menu on macOS).
