Install Access 2010 drivers
For backward compatibility reasons EwE6 uses Microsoft Access for its database system. Not all Windows systems are able to handle all Access database formats by default.
EwE will tell your if you cannot open accdb files. If this happens to you, please download and install the Microsoft Access Database Engine 2010 Redistributable from the Microsoft website. EwE should now be able to load both .ewemdb and .eweaccdb model files.
