Download U3 Launchpad Installer Executable

The easiest way I found is as follows. Open launchpad, type the app name in the search box at the top. The app should show up. Then click on the app and drag it down onto the page. That's all there is to it.
There are two ways to get an application to show up in the LaunchPad... one is to install the application in your Applications folder. This is where LaunchPad is looking for applications. It doesn't care if you got it through the App Store or if it's an Apple application or not. The second way is to drag the application over the LaunchPad icon residing on the dock and release it. This will create a symbolic link to the application without actually moving the application into the Applications folder. It has to be the application itself, not an installer for it, not a folder containing the application, the application. The application should be added to the LaunchPad if you don't rush it, hold it over the LaunchPad icon for a second or two.
Check to make sure it's not already in there... you won't see the LaunchPad dock icon do anything, you will just see the app you are dropping disappear. It could be on a second page. Click on the little dots when you launch LaunchPad to see if it's on one of the other pages.
@Baby Boomer: Actually, the basic "how to use the Launchpad" help page that you just blithely slapped in as a reply to the poster's question doesn't actually explain how to add things to the Launchpad, as the person was asking. It gives basics on how to use the Launchpad in general. Kind of surprising for a Level 9 guy....

If you are using Windows 8.1, and .NET 4.6.x is not installed, and you have not run Update KB2919355, the ACL for Windows installer terminates with an error message during the .NET 4.6.2 prerequisite installation.
If you have made changesto any of the sample projects or data files that you want to keep, savethe files elsewhere before installing or upgrading, or rename thefolder containing them. Do the same with the associated commandlog files if you want to preserve them.
The Analytics application executable uses a digital certificate chain to ensure its authenticity and integrity. The certificate chain requires an Internet connection to the third-party certificate authority so that the certificates in the chain can be verified. Your network firewall must allow access to the appropriate URLs associated with the certificate authority in order for this process to work. Without the required access, you will not be able to use Analytics.
If the ACL for Windows installer terminates with an error message during the .NET 4.6.2 prerequisite installation, you need to download and install Windows 8.1 Update KB2919355, restart your computer, and then restart the ACL for Windows installer.
Installing Machine Learning Services is not supported on an Always On failover cluster instance in SQL Server 2017. It's supported with SQL Server 2019 and later. You must install Machine Learning Services at installation time, and features can't be added to an existing failover cluster instance once installed.
Don't install Shared Features > Machine Learning Server (Standalone) on the same computer that's running a database instance. A standalone server will compete for the same resources and diminish the performance of both installations.
Side-by-side installation with other versions of Python and R is supported, but we don't recommend it. It's supported because the SQL Server instance uses its own copies of the open-source R and Anaconda distributions. We don't recommend it because running code that uses Python and R on a computer outside SQL Server can lead to problems:
Machine Learning Services is installed by default on SQL Server Big Data Clusters. You don't need to follow the steps in this article if you use a Big Data Cluster. For more information, see Use Machine Learning Services (Python and R) on Big Data Clusters.
After you finish setup, be sure to complete the post-configuration steps described in this article. These steps include enabling SQL Server to use external scripts and adding accounts that are required for SQL Server to run R and Python jobs on your behalf. Configuration changes generally require a restart of the instance or a restart of the Launchpad service.
For local installations, you must run the setup as an administrator. If you install SQL Server from a remote share, you must use a domain account that has read and execute permissions on the remote share.
On the Consent to Install Python page, select Accept > Next. The Python open-source license agreement also covers Anaconda and related tools, plus some new Python libraries from the Microsoft development team.
If the computer that you're using doesn't have internet access, you can pause setup at this point to download the installers separately. For more information, see Install machine learning components without internet access.
After setup is complete, if you're instructed to restart the computer, do so. It's important to read the message from the Installation Wizard when you finish setup. For more information, see View and read SQL Server Setup log files.
On the Consent to Install Microsoft R Open page, select Accept > Next. This license agreement covers Microsoft R Open, which includes a distribution of the open-source R base packages and tools. It also includes enhanced R packages and connectivity providers from the Microsoft development team.
After setup is complete, if you're instructed to restart the computer, do so. It's important to read the message from the installation wizard when you finish setup. For more information, see View and read SQL Server Setup log files.
Open the Services control panel item or SQL Server Configuration Manager, and verify that SQL Server Launchpad service is running. You should have one service for every database engine instance that has R or Python installed. For more information about the service, see Extensibility architecture in SQL Server Machine Learning Services.
Columns or headings used in the Python script aren't returned automatically. To add column names for your output, you must specify the schema for the return data set. Do this by using the WITH RESULTS parameter of the stored procedure, naming the columns, and specifying the SQL data type.
If you've added Machine Learning Services to an existing SQL Server instance and have previously applied a cumulative update (CU), the versions of your database engine and the Machine Learning Services feature might be different. This difference might result in unexpected behavior or errors because launchpad.exe and sqlservr.exe have different versions.
Run the installation of the cumulative update, and follow the instructions to install it for Machine Learning Services again. Select the existing instance where Machine Learning Services is installed. The upgrade status shows Incompletely Installed on the Feature Selection page.
If you install Machine Learning Services with a new installation of the SQL Server database engine, we recommend that you apply the latest cumulative update to both the database engine and machine learning components.
On internet-connected devices, cumulative updates are typically applied through Windows Update. But you can also use the following steps for controlled updates. When you apply the update for the database engine, setup pulls cumulative updates for any Python or R features that you installed on the same instance.
On the Feature selection page, review the features for which cumulative updates are applied. You should see every feature installed for the current instance, including machine learning features. Setup downloads the CAB files that are necessary to update all features.
If the external script verification step was successful, you can run R or Python commands from SQL Server Management Studio, Visual Studio Code, or any other client that can send T-SQL statements to the server.
In SQL Server 2019 on Windows, the isolation mechanism has changed. This mechanism affects SQLRUserGroup, firewall rules, file permission, and implied authentication. For more information, see Isolation changes for Machine Learning Services.
If you expect many users to run scripts concurrently, you can increase the number of worker accounts that are assigned to the Launchpad service. For more information, see Scale concurrent execution of external scripts in SQL Server Machine Learning Services.
To ensure that machine learning jobs are prioritized and resourced appropriately, we recommend that you use SQL Server Resource Governor to configure an external resource pool. You might also want to change the amount of memory that's allocated to the SQL Server database engine, or increase the number of accounts that run under the SQL Server Launchpad service.
Packages that you want to use from SQL Server must be installed in the default library that the instance uses. If you have a separate installation of Python or R on the computer, or if you installed packages to user libraries, you can't use those packages from T-SQL.
