Switch from .net 4.5 to 3.5

Hello, I've made a project using Visual Studio 2012 on Windows 7 64 bit. My client's computer is Windows XP 32 bit. So I searched for compatibilty issue and I learned that I might use .net 3.5 instead of .net 4.5

I did it but I'm getting an error. Here's a screenshot:

How can I fix this?

Edit: I attached the screenshot instead of linking to it.

Firstly, there's no need to use external file hosting to upload an image. You can attach it directly to your post.

As for the error message, it would have been nice if you had translated it into English for us. Regardless, I'm going to make a guess and say, as is the most common issue with Jet, your project is targeting the Any CPU platform and is therefore running in 64-bit mode on a 64-bit OS. There is no 64-bit version of Jet so it fails. If you want to use Jet on a 64-bit machine then the project must target the x86 platform so that it runs in 32-bit mode on all OSes.

thanks for the reply. that solved the problem.
