Msxml6.dll Failed To Register?

I am writing a very small application in VB.Net 2005.I added a reference to Microsoft.SqlServer.ManagedDTS so I can use a SQL Server 2000 DTS package on SQL Server 2005.I have one form with an Import at the top:

Imports Microsoft.SqlServer.Dts.Runtime ' needed for the DTS package to run

and under a start button I have:

Dim oApp As New Application

Dim oPkg As New Package[code]....

This works fine.The problem I am having is when I run the setup wizard to create a setup.In the build of the setup I get a popup that states:

The following files may have dependencies that cannot be determined automatically. Please confirm that all dependencies have been added to the project. C:winntsystem32msxml6.dll

Then when I run the setup program I get Module C:Program FilesMyCompanyNameSetupSMOmsxml6.dll failed to register, HRESULT -2147023782. Contact your support personnel, I ran regsvr32 msxml6.dll .
