Want to make a Invoice standalone software with sql local db

Question

I have developed an invoice software using windows forms and microsoft sql local db. In which I used dataset designer of microsoft to make a dataset. Dataset used to bind with datagrid and all the sql transactions are made through the dataset. so I cant use another datasource like sql compact datasource . Now I want to export the project as setup file and want to install on client machine without any need of sql server express.

I have already tried to deploy but after installing in client machine it shows error that cannot access the database.

 

I have installed .net 4.5 ,sqllocaldb.msi etc all required tools but nothing helped....

 

please help...

 

I want to know how a realtime softwares are devloping with database,I mean we only want to install setup.exe and it contain all the necessary files and run standalone a=in any machine
