How to deploy c# app on client computer

Question

Am having a problem deploying my c# application on client machine. I use advance installer for the setup.exe included with a database in the application, I use sql server 2012. When I run the setup.exe on my system it works properly also creating the database and all the tables in database query. I don't have any issue. But my problem is that when I try installing the setup.exe on another computer (client machine) the installation fail when query the database with this error: ODBC Connect: timeout exceeded, and the installation was unable to complete. Can you please put me through on how I can solve this problem and got the application installed on client's computer? Thanks so much..
