SYMPTOMS

Consider the following scenario:
  • You run a COM application on a computer that is running Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 SP1.
  • The application uses Neutral Apartment as the threading model for the COM objects.
  • The application encounters an error.
In this scenario, you may not receive correct rich error information. However, the rich error information that you receive helps you take necessary actions that are based on the error.

Note If the COM application uses the Free threading model for the COM objects, this issue does not occur.

CAUSE

This issue occurs because the errorInfo object is cleared and marked as NULL in the Neutral component that receives an interface pointer as an argument.

Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
