I have a .NET app (webforms - .NET 3.5) that is running on a 64-bit server as 32-bit (I checked the IntPtr.Size result). The compilation is set to AnyCPU so I would expect that on a 64-bit machine, the app would be run at 64-bit. There are many Third-party programs incorporated into the app, could they be causing a problem? How do I figure out why 64-bit compilation is not being done?

A:
I would check IIS to make sure that you have installed the 64-bit version. That is what determines how the ASP.NET applications run.

From my understanding, there is no such thing as 32bit IIS on 64bit Windows or 64bit IIS on 32bit Windows.

No there is. You can run 32-bit IIS using Windows on Windows.

You can run 32-bit worker processes in 64-bit windows. That's completely different than installing the 32-bit version of IIS in 64-bit windows. Also, @user54-64, you're right, you can't run 64-bit applications on 32-bit windows.
