Error in running ArcGIS Application

[rajabadsha]

Hi,
I am using Windows XP 32 bit OS with ArcGIS10.

I am encountering an error at run time. The error is occuring in the following line in bold.

Dim doc As IDocument = Nothing
        Try
            Me.Cursor = Cursors.WaitCursor
            Select Case cboApps.SelectedItem.ToString()
                Case "ArcMap"
                    doc = New ESRI.ArcGIS.ArcMapUI.MxDocumentClass()
                Case "ArcScene"
                    doc = New ESRI.ArcGIS.ArcScene.SxDocumentClass()
                Case "ArcGlobe"
                    doc = New ESRI.ArcGIS.ArcGlobe.GMxDocumentClass()
            End Select
        Catch
        Finally
            Me.Cursor = Cursors.Default
        End Try

I evaluated the line "New ESRI.ArcGIS.ArcMapUI.MxDocument" in the watch window and got the following message:

Run-time exception thrown : System.Runtime.InteropServices.COMException - Retrieving the COM class factory for component with CLSID {006B1AFE-C66C-11D0-B94C-080009EE4E51} failed due to the following error: 80040111.

This is an error with the library you are using, check the forums, a quick search brought up the error code a couple of times (ie here or here). Failing that, email them.
