Is it possible to connect to an Access Database (*.accdb) from within .NET application without having MS Access (not even redistributable engine) installed, but just packing ACEOLEDB.dll along application files?
I have revised my previous answer as I now realise that it was incorrect and I apologise for that. It was my experience that it was impossible to access a .accdb database without MS Access installed. Now I realise that if you have the access database engine installed than yes you can. However if this is not installed than no you can not have a working application that needs to interact with that type of database.
