FIX: Side-by-side COM DLL module manifest for Visual Basic 6.0 ActiveX Controls is overridden by the registry in Windows XP (843524)

SYMPTOMS

You can run Microsoft Component Object Model (COM) DLL modules in side-by-side (SxS) mode in Microsoft Windows XP. In SxS mode, different versions of a COM DLL module co-exist in the same computer environment without conflict. The COM DLL modules can co-exist because you use .manifest files that specify how your program binds to a particular COM DLL. The problem occurs when the registry overrides the .manifest file.

Microsoft Visual Basic 6.0 ActiveX Controls are essentially COM DLL modules with .ocx file name extensions. There is a hotfix that is supposed to provide support for dynamically-loaded Visual Basic 6.0 ActiveX Controls. However, this hotfix did not fix the problem that occurs when the interface information is read from the registry before the manifest is checked. If the interface information is found in both the registry and in the manifest file, the interface information is incorrectly read from the registry.
