we tried to register the Mail Components coming with Nav 5 on a machine running Nav 4 and a SQL Server. We also imported Codeunit 400 and its setup. The registration of the mail components was successfully.
Sending a mail from Nav 4 native database works fine. But when sending the same mail with the same objects imported in Nav 4 SQL database I get an error: “Automation instance couldn’t be created …” as if the registriation wasn’t did.
