Accessing Access 2010 (x64) .accdb database from WPF application (targetting x86)?

I have the following environment: Windows 7 Ultimate 64-bit MS office (with Access) 2010 64-bit

I am developing an application in VS 2010 and the application is being developed for x86 CPU. I am using DataSet to connect to the database and I am using the NewConnection wizard to connect to the database.

I want to use an access database for data storage. (.accdb file)

I downloaded and installed the Access Database engine (64 bit).

When i use:

Microsoft.Jet.OLEDB.4.0 - I get an error that the database format is not readable!!
Microsoft.ACE.OLEDB.12.0 - I get an error that the Microsoft.开发者_StackOverflow中文版ACE.OLEDB.12.0 driver is not registered on the local machine!

Please help me find a solution to the problem.

Since there is no answer, this is the solution applied: I installed the Access Database Engine, available as a download from Microsoft and it worked.

This was the latest version available and had the appropriate driver for database access.
