We're developing a WinForm app that is being deployed via ClickOnce. The application will have the ability to import/export data with the intention of this being done via SSIS. When this app is deployed and run against SQL Express, the following error gets generated:
“Retrieving the COM class factory for component with CLSID {E44847F1-FD8C-4251-B5DA-B04BB22E236E} failed due to error: 80040154”.
Is SSIS functionality supported in SQL Express

Very important question about SQL Express and SSIS
VFI Support
SQL Express does not include SSIS.
