Before I start, let me offer this link about SQL Server 2008 Express.

If you want to make your app run without dependencies on SQL Server 2008 then you code to not use SQL. Now it's an app just like others.

If you want to install missing support systems like SQL then you read the above link and start adding code to download and launch the installers for the missing support software.

I use MySQL for reasons I won't get into here but never created the code to install it for the end user. But I did supply an one page install document to get MySQL onto the target machine.

Maybe you need to learn about SQLite. Here's what they write about that.
"SQLite is a software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. SQLite is the most widely deployed database engine in the world. The source code for SQLite is in the public domain." https://www.sqlite.org/

Inno Setup is an excellent installer package. You can read more on their website: Click Here
