c# - Can i password encrypt SQLite database?

I am using SQLite database version 3 with C# Windows application..
i want to encrypt the SQLite database file using password or any other encryption way in order to prevent clients to open it from program files folder.

i don't want any runtime encryption ways, i just want to make the database file show password field when a client try to open it from the program files .. thanks

Edit

and if i encrypted it from code,the client can open it when the installation complete and db file transferred to the program files before opening the program to perform the encryption isnt it?

I use SQLite version 3 works perfectly!
You have to do that:

//if the database has already password
try{
            string conn = @"Data Source=database.s3db;Password=Mypass;";
            SQLiteConnection connection= new SQLiteConnection(conn);
            connection.Open();
            //Some code
            connection.ChangePassword("Mypass");
            connection.Close();
    }
//if it is the first time sets the password in the database
catch
    {
            string conn = @"Data Source=database.s3db;";
            SQLiteConnection connection= new SQLiteConnection(conn);
            connection.Open();
            //Some code
            connection.ChangePassword("Mypass");
            connection.Close();
    }

thereafter if the user tries to open the database. will say protected by Admin or the database is encrypted or is not a database or corrupted file!
