Hello, I have 2 features, one that includes SQL Server express and one that does not. I also have SQL Scripts I want to be installed AFTER the sql server is installed as a feature prerequisite.
The other problem I am facing is the SQL login for the sql scripts comes up directly after starting the install, instead of after SQL server pre-req install in the optional feature.
In order to run a SQL script depending on a feature state, you need to specify the Script Condition setting available in the Runtime tab. For example, the conditional expression "&MyFeature=3" evaluates to True only if MyFeature is changing from its current state to the state of being installed on the local computer, INSTALLSTATE_LOCAL.
Also, you may want to try sequencing the SQLLogin dialog with the forementioned condition after the ISInstallPrerequisites action in the InstallUISequence table so that the dialog is displayed after the SQL Server pre-req install.
