The Prerequisites Version Selection dialog box displays listing the required versions of the installed prerequisites. NOTE 1: For the Setup type - Client/FEP the Prerequisites Version Selection dialog box displays only when there is any conflict with the installed prerequisites in the system. It lists the required versions of the installed prerequisites and recommends you to install the required version, if the installed version is not compatible. NOTE 2: When you install the Server on a fresh system, by default, the prerequisite MicrosoftSQL Server 2019 - Express Editionis listed in the Prerequisites Version Selection dialog box. By default, the Install check box is selected indicating that it is recommended to install the prerequisite MicrosoftSQL Server 2019 - Express Edition. However, if you want to use another server, you can skip the SQL Express installation by clearing the Install check box. Even if you skip the MicrosoftSQL Server installation, the three prerequisites, Microsoft SQL Server 2012 - Native Client, Microsoft SQL Server 2016 - System CLR Types, and Microsoft SQL Server 2016 - Management Objects are installed on the server in the specified order. Installing these components help creating an HDB on remote server using SMC, when there is no SQL on the server. NOTE 3: If a compatible higher version of SQL is already installed on your computer, by default, the Installer skips the installation of the lower version of SQL (the Install check box is deselected).
