Find Missing dll
There was a question the other day in the vb.net newsgroup on how to make a list of the missing dlls on your system. Files that are registered by regsvr32 create a CLSID. This program will check all the CLSID registered dll exists and adds the missing ones to a list box.

End Sub
'Form overrides dispose to clean up the component list.

If Not (components Is Nothing) Then
components.Dispose()
End If
