DllNotFoundException for SQLite.Interop.dll (C# & SQLite)

I'm trying to get SQLite running in Visual Studio 2012 for C#. However after going through a set of tutorials I still get the error DllNotFoundException for the SQLite.Interop.dll.

This is the full error I receive:

Unable to load DLL 'SQLite.Interop.dll': The specified path is invalid. (Exception from HRESULT: 0x800700A1)

I have created a reference for the System.Data.SQLite.dll. Now I found that I have to add the SQLite.Interop.dll file into my project folder but I still get this error.

Oh and BTW, this is my code, if anyone is interested:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Data.SQLite;

namespace SQLiteWinFormCS
{
public partial class Form1 : Form
{

    private SQLiteConnection _sqlCon;
    private SQLiteCommand _sqlCmd;
    private SQLiteDataAdapter _db;
    private DataSet _ds = new DataSet();
    private DataTable _dt = new DataTable();
    private string _dbPath = String.Empty;

    public Form1()
    {
        InitializeComponent();
    }

    private void uiOpenDB_Click(object sender, EventArgs e)
    {
        Console(String.Format("You clicked {0}.", ((Button)sender).Name));
        this._dbPath = uiDatabaseFilepath.Text;
        Console("Filepath to DB = " + this._dbPath);

        Console("Attempting to open DB connection...");
        this._sqlCon = new SQLiteConnection(String.Format("Data Source={0};", @"\\Some-PC\ISC\Databases\testdbs\test.db3")); // << ERROR
        Console("DB connection succesfull!");

    }

    private void Console(string text)
    {
        uiConsoleOutput.AppendText(text);
        uiConsoleOutput.ScrollToCaret();
    }
}
}

Can anyone help me get this thing working?

Thanks in advance.

Copy the SQLite.Interop.dll file into your debug folder. For example "Projects\sqlite test18\sqlite test18\bin\Debug" place it here.

And dont add the Interop as a reference.

Add only these references

• System.Data.SQLite
• System.Data.SQLite.EF6
• System.Data.SQLite.EF6

This solved my problem. And I was using Sqlite x86 under x64 OS.
