OpenPlant C# Addin - Connect to Microsoft Access .mdb file in 64bit process

Hi,

I am developing a C# Addin for OpenPlant Modeler Connect Edition that reads data from the specification db (.mdb, Microsoft Access).

How OpenPlant connect to Microsoft Access Database (.mdb), for example the specification database?

Is there any API we can use inside a C# AddIn to read data from a .mdb file? 

C# AddIn requires 64bit version of Microsoft Access Drivers, but users PCs are using 32bit Office and they do not have administrative privileges…

Another problem we found is that the installation of 64bit drivers on a machine with 32bit drivers requires registry changes

This is explained in this article, for example: 

How to install 64-bit Microsoft Access database engine alongside 32-bit Microsoft Office | AutoCAD | Autodesk Knowledge Network

 Is there a way to avoid it?

Thanks
