Load/Run SSIS Packages On The Server From A .net Exe Exception:Microsoft.SqlServer.Dts.Runtime.DtsPipelineException: Retrieving.

Hello, I got an exception when I try to load/run a SSIS Package programmatically on the server using remoting.
The client machine has no SQL Server 2005 component installed..

This is the error I get from my exe application:

Microsoft.SqlServer.Dts.Runtime.DtsPipelineException: Retrieving the COM class factory for component with CLSID {E44847F1-FD8C-4251-B5DA-B04BB22E236E} failed due to the following error: 80040154.
---> System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {E44847F1-FD8C-4251-B5DA-B04BB22E236E} failed due to the following error: 80040154.
at Microsoft.SqlServer.Dts.Runtime.Application..ctor()

And this the Remote component:

<Serializable()> Public Class SSISComponent

Inherits MarshalByRefObject



Public Function LaunchPackage(ByVal sourceLocation As String, ByVal serverName As String, ByVal packageName As String, ByVal packageVariables As SortedList) As Microsoft.SqlServer.Dts.Runtime.DTSExecResult

Dim packagePath As String
Dim myPackage As Package
Dim integrationServices As New Application
' Combine path and filename.
packagePath = Path.Combine(sourceLocation, packageName)
Try
If integrationServices.ExistsOnDtsServer(packagePath, serverName) Then
myPackage = integrationServices.LoadFromDtsServer(packagePath, serverName, Nothing)
Else
Throw New ApplicationException( "Invalid package name or location: " & packagePath)
End If
If Not packageVariables Is Nothing Then
For Each de As DictionaryEntry In packageVariables
myPackage.Variables(de.Key).Value = de.Value
Next
End If
LaunchPackage = myPackage.Execute()
Catch ex As Exception
Throw
End Try
End Function
End Class

This is the code that call the remote component to run the package on the Server:
Public Class Test
Private Function LoadAndRunPackageRemotly(ByVal PackageName As String, ByVal PackageVariables As SortedList) As Boolean

Dim launchPackageService As New SSISComponent
Dim packageResult As Microsoft.SqlServer.Dts.Runtime.DTSExecResult
Try
packageResult = launchPackageService.LaunchPackage(Me.SSISPackageLocation, Me.SSISServerName, PackageName, PackageVariables)
If packageResult = DTSExecResult.Success Then
LoadAndRunPackageRemotly = True
Else
LoadAndRunPackageRemotly = False
End If
Catch ex As Exception
Throw
End Try
End Function
End Class

I would like to inform that everything run inside a thread because the Package do a lot of things...
When I build up the setup for the exe inside the Detected Dependencies there are several DLL related to SQL Server (Microsoft.SQLServer.DTSRuntimeWrap.dll etc..etc..) that I don't register ..
Tis could be the problem?
If yes, somebody can tell me which one I have to register ? as COM or COMRelativePath?
Some other hints?

This error could be also caused by wrong permissions on the ssis?
Thank you very much for any help...
p.s. To use sql server agent will be my last option!!
