Obtaining 10.2 Tokyo - Release 1

10.2 Tokyo - Release 1 is available as an installer (Feature Installer) and as an ISO (Offline Installer) from the registered users web page.

The installers for the 10.2 Tokyo - Release 1 are available for download on the following registered users download pages:

Installing 10.2 Tokyo - Release 1

  1. Run the installer. The installation wizard detects and uninstalls RAD Studio 10.2 Tokyo before installing 10.2 Tokyo - Release 1. Your settings will be preserved [1], but you can use the migration tool as a safety measure.
  2. Install 10.2 Tokyo - Release 1:
    • If you downloaded the Feature Installer, run the installer.
    • If you downloaded the Offline Installer, mount the ISO and run install_RADStudio.exe.

Installation can be performed through any of the following options:

  • Feature Installer: lets you select an initial set of RAD Studio features to install, such as support for specific combinations of programming languages and target platforms, language support, or help resources. Go to the Feature Installer for detailed information.
  • Offline Installer: lets you install RAD Studio on a system that does not have a working internet connection. After you install RAD Studio, the Offline Installer allows you to install additional features or remove installed features. Go to Using the Offline Installer for detailed information.


  • 1 To preserve your existing installation settings, it is recommended to install 10.2 Tokyo - Release 1 using the same installer (Offline Installer or Feature Installer) you used when installing 10.2 Tokyo. To determine which installer you used, verify if the IDE shows the Manage Platforms option under the Tools menu. If the menu item is available it means you used the Feature Installer.

  • Note: When the installation finishes, if you are asked to uninstall the Windows SDK, click Cancel. The versions of the Windows SDK in RAD Studio 10.2 Tokyo and RAD Studio 10.2 Tokyo Release 1 are the same.

    Updating the Platform Assistant

    The Platform Assistant server is required for cross-platform application development that targets either OS X or iOS. RAD Studio 10.2 Tokyo Release 1 contains new versions of the Platform Assistant installers (including setup_paserver.exe and PAServer19.0.pkg). The installer files are located in the PAServer folder.

    Uninstalling a Previous Version of the Platform Assistant

    On the Mac, it is not necessary to uninstall the Platform Assistant, but you can use the Move to Trash command if you want to remove the previous version.

    On Windows, use Uninstall PAServer.exe to uninstall the Platform Assistant (recommended). The Uninstall program is located in the installation directory for the Platform Assistant.

    Note: Several versions of the Platform Assistant can coexist on a system, as long as you run each version on a different port.

    Known Issues

    Installing IoT Components

    After upgrading to 10.2.1 from 10.2.0, you might see the following error message when installing an Internet of Things component from the GetIt Package Manager: "Problem when adding file "dcliotReg.pas" to the project."
    This is caused by some misalignment between the registry and the actual status of the packages.

    As a workaround, we recommend removing the folder C:\Users\<username>\Documents\Embarcadero\Studio\19.0\CatalogRepository\dcliot-250 and letting GetIt refresh it. Please note that using this approach, you will lose the configuration of other IoT components already installed on the system. As an alternative, you could copy the file above from the system, empty the folder, and then merge back the existing configuration.
