I get a strange exception when a window containing a GeckoWebBrowser is loaded.
This is the exception message:
An unhandled exception of type System.Runtime.InteropServices.COMException occurred in Skybound.Gecko.dll Additional information: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))
This is the windows code:
public partial class AddContents : Form
{
String path;
public AddContents(String path)
{
this.path = path;
InitializeComponent();
}
private void exitToolStripMenuItem_Click(object sender, EventArgs e)

this.Close();
}
private void AddContents_Load(object sender, EventArgs e)
{
geckoWebBrowser1.Navigate(path);

if (el != null) {
