A family of Microsoft relational database management systems designed for ease of use.
I have the same problem too! I have several computers running windows 7. One computer has Access 2013 which was used to build an application. This application is then shared with the rest of the computers which run Access 2013 Runtime.
Today I attempted to deploy a newer version of the database and all the computers running the Access Runtime were unable to open it. It appears Access updated itself to a version which breaks new accde files.
I attempted to roll back to a version several months old using integratedoffice.exe REPAIRUI RERUNMODE version 15.xxxxxxx but it failed to change the version number.
PLEASE FIX THIS IN THE NEXT UPDATE
