I just posted some information about this issue over in Nick's post from the other day. Hopefully, the additional details there will help to alleviate some of the frustration we're all dealing with on this one. To give some perspective, AutoCAD Electrical has always used Access MDB files so we've always relied upon the Access Database Engine. This goes back to before we purchased the product from VIA all those years ago. The recent shift in the way Office works, in general, is affecting any software vendor who has leveraged ODBC and other components of Office in their programs, us included. Our usage of the Access Database Engine is not unlike leveraging .NET Framework, Visual C++, or other programming structures that Microsoft makes available for all developers who make programs that run on Windows. At any point, a change to those underlying Windows components could impact all companies who rely on them for basic functionality. Some may call that arrangement a house of cards, and that (being a software company) we should just build/write everything ourselves, in-house to prevent having to rely on Microsoft substructures that can change without warning, but such is the software industry at this moment; we'll likely not be writing our own database engine driver any time soon. For now, our developers will continue to work on fixing this and all issues that affect our users, and I'll be here helping out on the Electrical support side of things. Thank you all.
