“microsoft.ac . oledb .14.0”提供程序没有在本地机器上注册

I have built a small WPF app that will read in XLS or XLSX files and display the contents in a datagrid. I have the XLS side of things working by using the Microsoft.Jet.OLEDB.4.0 provider. I am struggling with the XLSX side of things. I am running Windows 7 (64-bit) and have Office 2010 (64-bit) installed on my machine. I see the version 14 and 12 versions of the OLEDB in my ODBC connections. When I run my connection string it returns an error. I have read through many of the posts without any successful answers, many pointing to the version the app is running which is x86. I have tried both 14.0 and 12.0 getting the same error with respective version numbers.I have built a small WPF app that will read in
