Your operating system failed the launchpad prerequisites check. The following 32-bit GTK Library for running IBM Installation Manager is not available in underlying OS: list_of_missing_files. Please install the 32-bit GTK Library and restart your installation.
If you see this message, your server does not have the 32-bit version of the GTK library installed, or the library is an incorrect version. You must update your server with the correct version of the 32-bit GTK library before you continue the installation. You can get the library from the DVD or official website of your operating system.
Current system has detected a lower level of ulimit than the recommended value of recommended_value. Please increase the ulimit number to minimum value of recommended_value and re-start the installation.
Shutdown your installer. If you are a root user open a command prompt and issue ulimit -n recommended_value and then restart the installer. If you are a non-root user, work with your system administrator to increase your ulimit -n recommended_value and then restart the installer.
