Reading Outlook .msg files with VB.Net 2010 created program, on Windows 7 with Outloo

I am using the following code to get information from Outlook .msg files (created by Save As from
Outlook), such as .SenderName, etc., as shown in the code. This works on XP with Outlook 2007
on all but two of many .msg files.

I posted a problem on the not handling of those two files. This is a different problem.

I get an error when trying to access a .msg file when running on Windows 7 with Outlook 2010 installed.
The program was created, and the .msi built, on XP/Outlook 2007. The .msg files were created with
Outlook 2003 and 2007.

I get the following error:
System.InvalidCastException: Unable to cast COM object of type
'Microsoft.Office.Interop.Outlook.ApplicationClass'
to interface type 'Microsoft.Office.Interop.Outlook._Application'.
This operation failed because the QueryInterface call on the COM component for the interface with
IID '{00063001-0000-0000-C000-000000000046}' failed due to the following error:
The RPC server is unavailable. (Exception from HRESULT: 0x800706BA).
at System.StubHelpers.StubHelpers.GetCOMIPFromRCW(Object objSrc, IntPtr pCPCMD, Boolean& pfNeedsRelease)
at Microsoft.Office.Interop.Outlook.ApplicationClass.CreateItem(OlItemType ItemType)
at SearchDBs.frmMain.SearchAMSG(Int32 iThisDatabase)

I don't have a line number, but I think the error is on the following line:
oMail = CType(oOutL.CreateItem(Outlook.OlItemType.olMailItem), Outlook.MailItem)

Could this be because my program was created with a reference for Outlook 2007 instead of 2010?

I am not finding much with Google on reading .msg files with Outlook 2010 installed.

Any ideas of how to process the .msg files?

Thanks.

Code:

---

  Dim oOutL As New Outlook.Application
  Dim oMail As Outlook.MailItem
  Dim email As Outlook.MailItem

      oMail = CType(oOutL.CreateItem(Outlook.OlItemType.olMailItem), Outlook.MailItem)

      Dim MsgFileName As String
      MsgFileName = ChangeToSharedPath(gsDatabaseNames(iThisDatabase))

      email = oMail.Application.Session.OpenSharedItem(MsgFileName)

      With email
        AllOfMSGPreserveCase = .SenderName & .SentOn & .To & .CC & .BCC & .Subject & .Body
        AllOfMSGPreserveCase &= AttachmentsList
      End With
