Hi Greg Troyan,
Thanks for sharing the details and screenshots! Based on what you’ve described, the issue seems to be not about ExclusionGroup. The error VS_ISCORRUPT usually means the component metadata is invalid or incompatible in the runtime environment.
You can try:
- Run DTExec in 32-bit mode or Or in SQL Agent, enable (Use 32-bit runtime) in the job step
- Use ADO.NET Destination Instead of ODBC
- Try MySQL ODBC 8.0.33 or 5.3.14, which are widely tested with SSIS.
ExclusionGroup is an internal property for mutually exclusive precedence constraints. The error is misleading because the real issue is the component metadata corruption during validation in DTExec.
Hope this helps!
