Tasks for advanced installation
Before you perform an advanced installation, you must make sure that you have a user account with administrator privileges and that your system meets all system requirements. You might also want to uninstall any previous versions of XL C/C++ on your system. After you have finished installing the compiler, you must confirm that the installation has been successful and enable the man pages of the compiler.
