MVC Web服务返回-32位过程中不支持Microsoft SharePoint

Question

I am Trying to implement DocX to replace information from documents on a Document Library in Sharepoint using a web service. I am having difficulties because when I run my project and try to send information to the api address I get the following error

Microsoft SharePoint is not supported in 32-bit process. Please verify that you are running in a 64-bit executable. 

While debugging the code breaks on the following line

 using (SPSite site = new SPSite(siteurl))

I have found that I need to run the project on 64bit mode but if I choose that option the project does not run. I also found that the option Prefer 32bit cannot be checked but that option is disabled and not checked and finally in the IIS application Pool advance settings I need to turn into true the option Enable 32bit applications but it did not do anything.

None of the earlier have worked for me, I would like to ask for some help on solving this issue.

I am working on Sharepoint 2013, Visual Studio 2012 and MVC 4.

EDIT -

API Function

public class DocumentController : ApiController
{

    public DocModel Get(string docId, string docName, string docLibrary, string newDocLibrary)
    {
        DocModel document = new DocModel();

        try
        {
            string siteurl = "http://win-n1ni65gppp2/";
            using (SPSite site = new SPSite(siteurl))
            {
                using (SPWeb web = site.OpenWeb())
                {}

    }
        catch (Exception ex)
        {
            document.Message = ex.ToString() + "Perdistes";
            Console.Write(ex);
        }

        return document;
    }

}

Answer 1

Well the project was running on IIS Express and it seems that IIS Express does not compile 64bit applications on Visual Studio 2012.

I found this link that explains how to add some changes to the registry.

In the end just run the following code on the command prompt and restart the server.

reg add HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0\WebProjects /v Use64BitIISExpress /t REG_DWORD /d 1
