A family of Microsoft relational database management systems designed for ease of use.
There is a post earlier in the thread about msi installers.
The MSI installer is currently at an earlier version than 365 installer - hence it causes the issue in both msi and runtime vesions.
The issue also occurs in the latest 365 release if the files is opened as any other format than accdb i.e. accdr, accde etc.
I have seen no official release from Microsoft when this issue is going to be permanently fixed.
