If a non-Express supported edition (Standard, Enterprise, etc.) of SQL Server is already installed on your computer, we recommend that you select the existing instance to conserve both disk space and processing resources. For more information, search for
SQL Server best practices
in Help and Support. If you choose to use a different instance or to install a new instance, be sure to back up your database before you continue. After you complete the installation, start
Accounting CS
and restore the database. For more details, search for
Back up the firm database
