GUI WAY to install RPM:
Run your favorite file manager. Locate the rpm file. Next Right click on the RPM file and click on install. A window will come up asking you the root password. Type in the root's password. Mandrake 9 will install the RPM file and it will also check if it needs other rpm files.
An RPM file is the same thing as Windows Install Wizards.
