Enterprise environments frequently purchase specialized third-party SSIS components (such as those from CData Software or specialized EDI accelerators). These tools drag and drop directly into the SSIS toolbox, exposing EDI 835 segments as clean, flat database tables natively. Business Benefits of Automating SSIS-835 Data Flows
| Layer | What’s Happening | |-------|------------------| | | The Microsoft Access Database Engine (ACE) ships as two separate binaries: 32‑bit ( ACEODBC.dll / ACE*.dll ) and 64‑bit . They are not side‑by‑side; installing the 32‑bit version overwrites the 64‑bit one and vice‑versa. | | SSIS Runtime | SSIS packages can run 32‑bit or 64‑bit . The default on modern servers is 64‑bit . The runtime loads the exact version of the provider that matches its own process architecture. | | Package Design | If you built the package on a dev machine using the 32‑bit ACE driver (common when you install only the Access Database Engine Redistributable), the package metadata stores the ProgID Microsoft.ACE.OLEDB.12.0 . When the package is executed on a 64‑bit SSIS server without the 64‑bit driver , the provider cannot be instantiated → SSIS‑835 . | | Azure‑SSISIR | The Integration Runtime container is 64‑bit only; you cannot switch it to 32‑bit. Therefore, any ACE‑based component must use the 64‑bit driver, or you must refactor the data flow. | | Security Context | Even when the driver exists, the account running the SSIS job may lack read/write permissions on the underlying file (Excel, Access). The provider then returns a generic 0x80004005 unspecified error , which surfaces as SSIS‑835. | SSIS-835
