The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.

The documentation states MS Access drivers (including the OLEDB driver) only work under the x86 platform and is incompatible under the x64 or AnyCPU platform. However this appears to be untrue. Ref: https://stackoverflow.com/a/32760211/495455

First download the Microsoft Access Database Engine 2010 Redistributable making sure you tick the _64.exe version: http://www.microsoft.com/en-us/download/details.aspx?id=13255

1. Extract the AccessDatabaseEngine_x64.exe to a folder to get the AceRedist.msi and Data.cab files.
2. Open command prompt in Admin mode
3. cd to the folder you extracted the download and execute the MSI with the passive argument:

AceRedist.msi /passive

After these steps you should be able to run the application after building in x64 or AnyCPU build configuration.
