Windows Error Reporting does not function correctly when it is running in a "Windows on Windows 64" (WoW64) configuration on a Windows Vista SP1-based or Windows Server 2008-based computer

Windows Error Reporting does not function correctly when it is running in a "Windows on Windows 64" (WoW64) configuration on a Windows Vista SP1-based or Windows Server 2008-based computer. WoW64 is a component of 64-bit Windows-based operating systems that enables 32-bit applications to run.

If a user sends information to Microsoft about a specific error by using the Windows Error Reporting interface on a WoW64-based computer that is running Windows Service Pack 1 (SP1) or Windows Server 2008, Microsoft does not receive the information. This information is used to analyze the error. This information could lead to a solution for the specific error that would be posted in the Problem Reports and Solutions item in Control Panel.

This problem occurs because of a bug in the WerReportHang API that is corrected in this update. This problem only occurs on computers that were upgraded from the original version of Windows Vista to Windows Vista Service Pack 1 or on computers that are running the original version of Windows Server 2008.
