You need to install Access Database Engine. More details Office Microsoft Access Database Engine 2010 Redistributable

If your project use x86 LinqToXml install x86 otherwise x64 version of Access Database Engine. For x64 Windows and x64 Office can be used also x86 LinqToXml and Access Database Engine.

I successfully test this on

• Win 64, Office 64, Access Database Engine 64, LinqToXml 64 and output target project x64
• Win 64, Office 64, Access Database Engine x86, LinqToXml x86 and output target Any CPU.
