Calling SSIS package from .Net

I am calling SSIS package from a .Net windows UI. Both SSIS & .Net app are created in 2008. The SSIS package is stored in file system. When I ran .Net app I got error:

The package failed to load due to error 0xC0011008 "Error loading开发者_Python百科 from XML. No further detailed error information can be specified for this problem because no Events object was passed where detailed error information can be stored.". This occurs when CPackage::LoadFromXML fails.

The code that I am using is very simple:

string packageLocation;
Package ssisPackage;
Microsoft.SqlServer.Dts.Runtime.
Application ssisApplication;
DTSExecResult ssisPackageResult;
packageLocation =@"D:\SSISCall\Package.dtsx";
ssisApplication =new Microsoft.SqlServer.Dts.Runtime.Application();
ssisPackage = ssisApplication.LoadPackage(packageLocation,null); ----Getting error here
ssisPackageResult = ssisPackage.Execute();
Console.WriteLine(ssisPackageResult.ToString());
Console.ReadKey(); 

Please suggest.

Do you have SSIS components installed on the computer where you are executing this package? If not, it won't run - see http://msdn.microsoft.com/en-us/library/ms403348.aspx

Is the version of SSIS installed on the computer 2008? If not, it won't run - 2005 and 2008 parts are not interchangeable.

Is drive "D" a mapped drive? If so, your code probably won't run unattended (with a not-logged-in user session) - use UNC paths instead.

Getting exactly same error on the Lame loadPackage call.

This code was working fine for SQL 2005.

EnvDTE90 doesn't look like add any functionality to the DTS Application model.

Referencing both EnvDTE80 and EnvDTE90 doesn't make any differnece
