SSIS error codes can vary widely, and they often relate to specific issues within the SSIS environment, such as problems with package execution, connection issues, data type conversions, or component failures. The "SSIS-835" error code might be associated with a particular type of failure or warning that occurs during the execution of an SSIS package.
To troubleshoot an issue like this, here are some general steps you can follow:
Check the Error Description: The error message usually provides more details about the nature of the problem. Look for any additional information or error messages that might describe the issue more clearly.
Review the SSIS Package: Look at the package in the Visual Studio (or Visual Studio for Applications) environment. Check the components involved around the point of failure. Ensure that connections are properly configured, and data types are compatible.
Variables and Parameters: Verify that variables and parameters are correctly set. Sometimes, errors occur because a variable or parameter has an unexpected value. SSIS-835
Event Log and Output: The Output and Event Log windows in Visual Studio can provide additional information about what went wrong.
Connections and Permissions: Ensure that all connections (e.g., to databases, files) are valid and that the account under which SSIS is running has the necessary permissions.
Data Flow: If the error occurs in a data flow task, check for potential issues like truncation of data, incompatible data types in source and destination, or incorrectly configured transformations.
Online Resources: Microsoft's documentation and community forums can be invaluable resources. There might be specific advice or known solutions related to the "SSIS-835" error. SSIS error codes can vary widely, and they
Logging: Consider enabling more detailed logging for your SSIS package to capture additional information that might help diagnose the issue.

| Layer | What’s Happening |
|-------|------------------|
| ACE Provider | 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. |
Bottom line: SSIS‑835 is a provider‑mismatch problem, not a “bad data” problem. Check the Error Description : The error message
| # | Scenario | Why It Happens |
|---|----------|----------------|
| 1️⃣ | Dev → Prod migration – The package was built on a dev laptop with the 32‑bit ACE driver, then deployed to a production SSISDB that only has the 64‑bit driver. | Provider cannot be instantiated. |
| 2️⃣ | Azure Data Factory (ADF) → Azure‑SSISIR – The SSISIR is 64‑bit only, but the package still references Microsoft.ACE.OLEDB.12.0. | Same mismatch, plus no easy “Run in 32‑bit mode”. |
| 3️⃣ | SQL Server 2022 on Windows Server 2022 – You installed the Access Database Engine 2016 Redistributable (32‑bit) to satisfy another app. The 64‑bit driver is missing. | SSIS runs 64‑bit → driver missing. |
| 4️⃣ | File path / permission issue – The Excel file lives on a network share that the SSIS service account can’t reach. The provider throws a generic COM error that appears as SSIS‑835. | Not a driver issue, but the error mask looks identical. |
| 5️⃣ | Mixed‑mode packages – Some data flows use ACE, others use ODBC. The package runs with Run64BitRuntime = False in Visual Studio, but the deployment uses the default 64‑bit runtime. | Inconsistent execution mode. |

TL;DR – SSIS‑835 is the “Data Flow task failed because the source component returned an error: “The OLE DB provider “Microsoft.ACE.OLEDB.12.0” reported an error.”* error that typically pops up when you try to read from or write to an ACE/Jet‑based file (Excel, Access, Text) inside an SSIS package that is running on a SQL Server 2022+ or Azure‑SSISIR environment. The root cause is a mismatch between the 32‑bit ACE driver and the 32‑bit/64‑bit execution mode of the SSIS runtime. The fix is to standardize on the 64‑bit ACE driver, switch the package to 32‑bit mode, or replace the ACE source/destination with a more robust alternative (e.g., CSV → Flat File Source, Power Query, or Azure Data Factory).
