AEM 5.6.1.SP2 Dispatcher not working on Windows Server 2012 R2

[ginosafilo]

We are trying to setup the dispatcher on an AEM Publish instance.

Our server configuration:

• AEM version: AEM 5.6.1.SP2
• OS: Windows Server 2012 R2 (64 bit OS and x64-based processors)
• Application server: IIS 8.5
• Dispatcher version: 'dispatcher-iis-windows-x64-4.1.10.zip'

We followed the official Adobe docs at https://docs.adobe.com/content/docs/en/dispatcher/disp-install.pdf
However, we still have these (non trivial) problems.

1. Seemingly, IIS cannot load disp_iis.dll, since when we try to visit the root URL, requests aren't forwarded to CQ (that is, the default IIS webpage is displayed).
2. Upon IIS start, the "dispatcher.log" file isn't generated (this is due to the previous error).

In the Windows event log, this error message is created:

    The http Filter DLL C:\inetpub\Scripts\disp_iis.dll failed to load. The data is the error
    
The full error in XML format is:

<Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="Microsoft-Windows-IIS-W3SVC-WP" Guid="{670080D9-742A-4187-8D16-41143D1290BD}" EventSourceName="W3SVC-WP" /> <EventID Qualifiers="49152">2214</EventID> <Version>0</Version> <Level>2</Level> <Task>0</Task> <Opcode>0</Opcode> <Keywords>0x80000000000000</Keywords> <TimeCreated SystemTime="2015-09-21T14:47:47.000000000Z" /> <EventRecordID>14725</EventRecordID> <Correlation /> <Execution ProcessID="0" ThreadID="0" /> <Channel>Application</Channel> <Computer>...</Computer> <Security /> </System> <EventData> <Data Name="IsapiFilter">C:\inetpub\Scripts\disp_iis.dll</Data> <Binary>7F000000</Binary> </EventData> </Event>
