If you choose to install a new instance of Microsoft SQL Server 2012 Express Edition, mark the option and select
Next
to install and configure the instance for use with DT Practice. You will need to provide a unique name for the new instance. Select
Next
to specify where you want your DT Practice database to reside. This cannot be a network folder. SQL requires this folder to be on this computer.
If DT Practice has been previously installed, you can select the instance used during the last installation, unless that instance is older than version 2012. If you choose to use a different instance or install a new instance, you must back up your database before continuing. After installation is complete, start DT Practice and restore your database.
