Figure 5-3
The default selections on this screen are adequate for most requirements so unless you have specific needs there is no necessity to alter these selections. Continue to the next screen, review the information and click Install to begin the installation. Note that you may first be prompted to enter your password as a security precaution. The duration of the installation process will vary depending on the speed and current load on the computer, but typically completes in 25 - 45 minutes.
