You can start the installation process for SQL Server 2008 RC0 by selecting the Install option in the SQL Server 2008 RC0 Installation Center and then choosing to install a standalone instance.
Setup will first perform some installation requirements checks, including operating system version, installation permissions, and so on, through the Show Details button to understand the results of the inspection. If a check entry fails, the Status column allows you to see the detailed results of the entry.
Check through, the user will need to choose the installation version, if there is no corresponding serial number can only choose the evaluation version, if there is a serial number, you can enter the serial number. After the serial number is entered, the installer automatically confirms the version that was installed. This is also a small change in the installation of SQL Server 2008, as is the case with Windows Server 2008, Vista, which can be very effective in managing the excessive amount of media.
After you enter the serial number or select the installed version, the Setup Wizard displays the license agreement, but if you want to continue the installation, you can only accept it.
