SYMPTOMS

You install a product that updates the Mfc80.dll module or the Mfc80u.dll module on the computer from version 8.0.50727.870 to version 8.0.50727.3078. For example, you install Microsoft SQL Server 2008. When you run an application that is built with Microsoft Visual Studio 2005, an access violation occurs in the Mfc80.dll module or in the Mfc80u.dll module. And, the application crashes.

Note This problem applies to many other applications, including applications that are used on Windows 7.

CAUSE

This problem occurs because the two versions are incompatible.
