I am trying to read an xlsx file.

I got exception that 

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

then I installed it from here 

http://www.microsoft.com/en-us/download/details.aspx?id=13255

then I changed the platform target to x64

now i got this exception:

BadImageFormatException was unhandeled

{"Could not load file or assembly 'LinqToExcel, Version=1.9.0.0, Culture=neutral, PublicKeyToken=9c8ea65a58f03f1f' or one of its dependencies. An attempt was made to load a program with an incorrect format."}

Update 1

I already installed the linq_to_excel using 

Install-Package LinqToExcel

and then add the lib files to references
