64bit

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?
