Error When Making Call

[scking]

I've built a .dll from .NET using the System.IO.FileInfo namespace that builds a solution but, when called from VBA, generates and exception. It's a very simple class but has me blocked. If anyone could provide me an answer I would appreciate it.

Request for the permission of type System.Security.Permissions.FileIOPermission, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed.

Public Class Class1
<ComClass(Class1.ClassId, Class1.InterfaceId, Class1.EventsId)> Public Class Class1

Public Const ClassId As String = "B9E2B29C-62B6-4b2c-B4A2-3D1597B76A0F"
Public Const InterfaceId As String = "8B8332ED-6A57-45fd-A301-D60DA372351B"
Public Const EventsId As String = "9CFE452E-BAD3-49b6-B5E6-2FBADEEC0E8F"

Public Function FileExists(ByVal Filename As String) As Boolean

Dim objFileinfo As System.IO.FileInfo
Dim strFilename As String = Filename

objFileinfo = New System.IO.FileInfo(strFilename)
If objFileinfo.Exists Then
Return True
Else
Return False
End If
End Function
End Class
End Class
