SQL Server Compact edition 3.5 database acess is denied

Question

I have developed a desktop application in C# with Microsoft SQL Server Compact Edition 3.5.

It works fine when I run .exe file from solution folder ( bin\\release or debug ) but when I tried to deploy it by creating its setup it shows unhandled exception:

You don't have permission to access CustomersDB.sdf file.

Note there is no path error it is correct.

string lokasifile = Environment.CurrentDirectory + "\\CustomersDB.sdf";
string stringkoneksi = "Data Source = \"" + lokasifile + "\"";
SqlCeConnection koneksi = new SqlCeConnection(stringkoneksi);
koneksi.Open();

Answer 1

SecurityException 

This is nothing but caller does not have the appropriate permission. Environment.CurrentDirectory Property

try
{
     //Call Path here you will get to what the exactly error is
}
catch (Exception ex)
{
     if (ex is DirectoryNotFoundException|| ex is IOException|| ex is SecurityException)
     {
          //Your handling here
     }
     else
     {
          throw;
     }
}
