You cannot distribute hotfix versions of the Microsoft Visual C++ runtime by using the Microsoft Visual C++ 2005 Redistributable Package. Additionally, any hotfix version of the Visual C++ 2005 Redistributable Package does not install the .pdb files.


This issue occurs because the runtime fixes are typically distributed by using merge modules. This behavior is by design. However, initial distribution of the runtime is sometimes performed by using the Visual C++ 2005 Redistributable Package. This initial distribution does not support side-by-side deployments and does not handle complex versioning situations.
