Could not load file or assembly 'LinqToExcel, Version

Question

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

Which version of the Microsoft Access Database Engine did you install? If you installed the x64, I'd try uninstalling it and installing the 32 bit version. — Mick, Aug 11 '14 at 02:14

You have two options to solve

Enable IIS to run 32 bits app
Install LinqToExcel_x64
