General Installation Notes

Installer Requires Additional Temporary Space

If the drive containing the folder specified in your TEMP environment variable is low on space, the installer might halt with an error message noting the shortage. If this occurs, assign your TEMP variable to a folder on a drive with more disk space, then re-run the installation.

It is also possible to change the path of the installer cache directory by using the command line Setup.exe OVERRIDECACHE=<new-path-to-cache>. However this is completed at the user's own risk, Embarcadero cannot be responsible for any issues raised as a result of using this command.

For more information, see System Requirements.

Software that You Can Install Using the Product Installer

The installer program installs the product and optionally the product Help system.

The following third party products are installed as part of the main product:

Android 5.1.1. Support

If you choose not to install Android NDK during the RAD Studio installation and you have problems with debugging an Android application on the device with Android 5.1.1, try the following:

  1. Go to Tools > Options > Environment Options > SDK Manager > Android SDK > NDK tab > gdbserver location
  2. Take note of the path in gdbserver location.
  3. Download and install the new Android NDK: android-ndk-r10e (use this link).
  4. Rename the current gdbserver file (from step 2) to gdbserver.r9c
  5. Copy the newly installed <android-ndk-r10e>\prebuilt\android-arm\gdbserver\gdbserver to the location from step 2.

Separate Install Required for Several Elements of the Android SDK

Several required elements of the Android SDK are not installed during RAD Studio installation.

When you first attempt to build an application for Android, RAD Studio prompts you to install the required elements of the Android SDK.

You must accept a standard license agreement, and then the required elements are installed.

The required elements of the Android SDK include:

  • platform-tools
  • build-tools-21.1.2
  • android-21 (Lollipop support)

Java and the JDK: The RAD Studio installer installs Java and the JDK by default if you do not already have Java 1.6, 1.7, or 1.8 installed.

For more information, see Installing the Android Development Tools.

FireMonkey Platform Requirements

Applications developed using FireMonkey have specific platform requirements, such as for the Graphics Processing Unit (GPU). For details, see FireMonkey Platform Prerequisites.
