The Launcher perspective toolbar contains functions that are generally useful throughout Simplicity Studio® 5 (SSv5).


The Tools button opens a dialog where you can select a tool to open it, and also add and remove tools.

The Add/Remove Tools link opens the Installation Manager. Click Manage Installed Packages and go to the Tools tab, where you can add and remove tools.


The Install button (red when updates are available) opens the Installation Manager.

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. The interface opens on the Updates tab. Updates are grouped by type.

The SDKs tab supports installing and uninstalling SDKs and supporting packages. Summary release notes are provided. Filters across the top of the dialog allow you to control the items displayed.

Note: The default Version filter is 'Latest'. To see and install earlier versions, change this to 'All'.

If you have access to the item Access Granted is noted in green, and the item has an Install control. If you do not have access, the item has a Request Access control that opens a web page where you can contact sales. Installed items have an Uninstall control in red. Some installed items cannot be uninstalled because other items are dependent on them.

The Early Access tab is used to provide limited access for some customers, usually for beta testing.

The Tools tab shows available and installed tools, regardless of your connected or selected hardware. Summary release notes are provided.

The Assets tab shows available assets. Assets include items such as documents, photographs, code, and so on. Check the item(s) of interest and click Install. The default view is filtered by connected product.

The unfiltered view provides a much larger set of options.

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.

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).

Frequently used preferences are discussed in context of their use cases. Context-sensitive help is available for most preferences.

The arrow controls in the upper-right enable navigation through previously viewed pages. To return to a page after viewing several pages, click the drop-down arrow to display a list of recently viewed pages.

If you have made changes in preferences and wish to move them to a different installation, use the Import and Export controls in the lower left.
