Ran into the following Microsoft Dynamics CRM 2016 On-Premises error when trying to access Microsoft CRM via the Web Client:

HTTP Error 500.0 – Internal Server Error.  Calling LoadLibraryEx on ISAPI filter “C:\Program Files\Microsoft Dynamics CRM\Server\bin\DefaultAddonFilter.dll” failed

This is a CRM development environment that was running OK until we setup the CRM BIDS on it to build SSRS custom CRM Reports.  During the Microsoft Dynamics 365 Report Authoring Extension installation – the required component Microsoft Online Services Sign-in Assistant installed the Microsoft Visual C++ 2013 Redistributable (x86), however part of the installation logic removed the existing Microsoft Visual C++ 2013 Redistributable (x64) version which is needed for the Microsoft Dynamics CRM Server 2016.

Without the Microsoft Visual C++ 2013 Redistributable (x64) version on the CRM Server – will result in HTTP Error 500.0 – Internal Server Error.  Calling LoadLibraryEx on ISAPI filter “C:\Program Files\Microsoft Dynamics CRM\Server\bin\DefaultAddonFilter.dll” failed message.

The fix is to re-install the Microsoft Visual C++ 2013 Redistributable (x64) version on the CRM Server.   No more error message. Yay!
