SQL 2016 Agent 32-bit issue

I've read several fixes for this issue but it still seems to persist.  I have:

- SQL 2016 (SP1) v13.0.4001

- Old Pervasive 32-bit driver to a Timberline DB

- SSIS Config Prop > Debugging > 64BitRuntime set to False (although it defaults to True upon reopening project)

- Deployed to Integration Services Catalog

If I manually run Master package from Catalog, and manually check 32-bit setting (it never stays checked), all packages execute successfully

If I schedule through Agent, which is configured to run as 32-bit..

Packages always fail at the same spot with the same message.  Any ideas are welcome.
