title: Can someone help me with IIS and ODBC?
body: <p>I have a problem with a 64 bit ODBC Source. I developed a simple website with a button. OnClick connect to a 64 bit ODBC Source. If I run this with the Visual Studio 2019, it works fine. But before I must change the Server Platform to 64 bit at properties/web Bitcount....</p>
  
  <p>If I deploy the project to the localhost IIS. I do not get a connection.</p>
  
  <p>I think the IIS do not work at 64 bit? </p>
  
  <p>Yes it is a Windows 64bit platform. I tried it at a Windows 10 and a Windows 7 64bit platform. I do not configured the Application Pool. I tried the configuration at the advanced settings but i revoke it.</p>
