Click Next to continue.
To proceed with the installation, you may be required to provide a service account password. If prompted, provide the password and click Next to continue.When the Ready to Install dialog (shown in Figure 2.4) informs you that the installation is about to begin, click Next to continue.The setup wizard displays progress bars to inform you of each component that is being installed (see Figure 2.5).The PEM Agent Setup Wizard will inform you when the installation completes (see Figure 2.6). Click Finish to exit the wizard and close the window.
