These assemblies are installed with Microsoft Office. You can: * Install Microsoft Office OR * Download the '''Redistributable Primary Interop Assemblies''' from [http://www.microsoft.com/downloads/details.aspx?familyid=59daebaa-bed4-4282-a28c-b864d8bfa513&displaylang=en Microsoft] and install these separately. == !BadImageFormatException was unhandled == This exception indicates a corrupted build environment. Perform the following: * '''Build > Clean solution''' * '''Close Visual Studio''' * manually '''delete''' any ''obj'' and ''bin'' folders from the sources folder tree. == !InvalidOperationException was unhandled == A possible cause for this exception is a 64-bit incompatibility problem with the .NET and the Microsoft Access drivers. To overcome this problem, EwE6 must be compiled for 32 bit processors. Do the following: * Select {{{Build menu > Configuration Manager}}} * Select {{{Active Platform}}} to '''x86''' (new if not listed).
