PB 12.6 64 bit deploy & OLE DB (not)

I'm working on migrating a 12.5 to 12.6 app.  The app connects to MS SQL Server  2012 via OLE DB

Once migrated, the app connects fine when deployed as 32 bit pCode

Then I build a simple POC to test 64bit connectivity.  MSS 64 bit Client is installed. Connectivity fails.

Then a colleague notices on Runtime Packager that OLE DB driver is disabled when 64 bit is connected!

I switch to SNC driver and can connect fine.  Will I need to change my driver support?

Doc does not mention anything about NO 64 bit support.  Just says

"The OLE DB interface uses a DLL named PBOLE126.DLL to access a database through an OLE DB data provider"

What's going on here?

Thanks
