ManagedPipelineHandler - HttpStatus 500 Notification 128 Internal Server Error - Microsoft ASP.Ne...

We have designed a ASP.Net WebAPI written in C# hosted on IIS 7.0 - REST style architecture. This is working in several environments, but is failing on a SBS 2008 environment with IIS 7.0. This interface must work with a Application Pool that is Enabled
to work with 32-Bit Applications.
We have this Webservice working in 2012 Essential Server and a 2008R2 Standard both with IIS 7.5.
The initial errors as logged with Failed Requests showed 500.19 errors. These were failures with the Static/DynamicCompressionModules. These were cleared-up by deleting these modules. After these errors cleared, an error with HTTPStatus 500, ModuleName:
ManagedPipelineHandler, Notification: 128, HTTPReason: Internal Server Error displayed. The Notification is EXECUTE_REQUEST_HANDLER with ErrorCode: The operation completed successfully. (0x0).
Fiddler reports:

I don't know but I think it might be something to do with how the COM objects are created.
IIS7.0 will run on Windows 2008 (not R2) are often 32bit. What version of you running?
I expect this is causing issues for you. Maybe something is created for x64 rather than x86.
You could try running it in classic app pool too.
