Ssis-835 Jun 2026

The SSIS-835 error is a common issue that occurs when working with SQL Server Integration Services (SSIS). This error code is typically associated with a problem in the package execution, and it can be challenging to diagnose and resolve.

| # | Scenario | Why It Happens | |---|----------|----------------| | 1️⃣ | – 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. | SSIS-835
