Inno setup installation

I made a WPF app which I can install on other computers, everything works fine except for database access. Currently, I have a sqlite database on my computer and the connection string for this database is specific to my computer.

I am able to run my application on other computers if I manually create the same directory structure where the database is stored.

How can I make an installer which allows me to choose the destination of the database?

How can I get the new connection string for this new database?

Thanks in advance !
