| Property | Value | |----------|-------| | | 171 | | Message (SQL Server 2019+) | “The package failed validation. The package contains a component that is not supported on the target platform.” | | Typical Source | Data Flow → OLE DB Source / Destination, ADO.NET, Script Component, or any custom component that was built for a different SSIS version/bitness. | | Why It Happens | The runtime engine (DTExec / SSIS Catalog) cannot locate, load, or run the component because of one (or more) of the following mismatches: 1. Version mismatch – component compiled for SSIS 2008/2012 but running on SSIS 2019+. 2. Bitness mismatch – 32‑bit component on a 64‑bit run‑time (or vice‑versa). 3. Missing assembly – DLL not present in the GAC or in the C:\Program Files\Microsoft SQL Server\150\DTS\Binn folder. 4. Platform target – the package was saved as “SQL Server 2008” (or an older version) but is being executed on a newer server that enforces “TargetServerVersion”. | | Impact | Package validation fails before any data moves . The package never starts, and the SSIS Catalog logs the error with severity 16. |
The SSIS-171 error code may seem like an enigma, but by understanding its possible causes, following troubleshooting guidelines, and applying solutions, you can overcome this frustrating error and ensure the smooth execution of your SSIS packages. By adopting best practices and regularly reviewing package configurations, you'll be well on your way to minimizing the occurrence of SSIS-171 errors and achieving greater success with your data integration projects.

The SSIS-171 error can occur due to a variety of reasons. Some of the common causes include:
When the SSIS-171 error occurs, you may experience the following symptoms:
| ✅ Preventive Action | How to Implement | |----------------------|-------------------| | | Add <TargetServerVersion>SQLServer2022</TargetServerVersion> to the .dtproj and check‑in the project file in source control. | | Enforce 64‑bit Development | In the Solution → Properties → Debug , set Run64BitRuntime = true and make it a team‑wide Visual Studio setting (via a .vsconfig file). | | Package‑Level Component Whitelisting | Create a PowerShell validation script that scans the .dtsx for any component whose classID is not in an approved list. Fail the CI build if it finds a rogue component. | | Automated Deployment of Third‑Party DLLs | Use a SQL Server Agent job or Octopus Deploy step that copies the required DLLs to DTS\Binn and runs gacutil /i . Keep the DLLs version‑controlled. | | Continuous Integration (CI) Validation | Add a MSBuild /t:Validate step in your build pipeline (SSDT 2022+ supports /t:Validate ). Capture the output; any 171 will break the build. |
If you must run 32‑bit (e.g., legacy Jet/ACE drivers), set it to false and also edit the SQL Agent job step:
