a db created using a2019 cannot be opened in a2007, since there are Newer system tables
in a2019 that cannot be found in a2007.

if the original db was created in a2007, then modified the code/tables in a2019, it
might not be compatible with a2007 anymore.
Thank you, but not the answer. They have the same version of software running successfully on A2007 and A2019 workstations. This is a third machine which is also A2007. It is a new workstation using the same version of Windows as the other two. Because the workstation being replaced had A2007, the tech reloaded A2007 on the new workstation. All other things are equal. I personally copied the version running on the other A2007 machine directly to the new workstation. It ran on the first A2007 workstation and was an unrecognized database on the second.
