Answer 1

For me, my problem came because of a setting in my project's web.config file (and also the solution, once I understood the problem).

In my web.config file, we had these two lines in the system.webServer > handlers area:

<remove name="WebServiceHandlerFactory-ISAPI-2.0" />
<add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

Notice the alternative handler has the attribute 'preCondition="integratedMode"'. So, I had to change my AppPool to use Integrated instead of Classic for my pipeline mode setting (which is the opposite of what the solutions above told me to do).

• Right click the application pool used by your website.
• Click on Advanced Settings...
• Set "Enable 32-Bit Applications" to True.

I think this was because the web application was compiled for 32 bit only.
