The installer relies on temporary files it copies to your machine. Ensure you have enough space allocated to accommodate these temporary files.
The temporary files require approximately 220 MB of free space. By default, the installer copies the files to your /tmp directory.
You can install the files to a different location by setting the environment variable IATEMPDIR to point to a different directory.
Whether you use the default /tmp directory or an alternate directory, you can safely delete files remaining after installation to free up disk space.
