KB2538242 Win 10: Solving Issues with Visual C++ Redistribution

When it comes to installing updates, especially those related to Microsoft Visual C++, things can get complicated. In this article, we'll explore a specific issue with the KB2538242 and KB2538243 updates, which caused problems for users trying to install them on their Windows 10 systems.

The issue began when users attempted to install the 32-bit version of KB2538242, only to find that it prevented the installation of the 64-bit version. Despite multiple attempts at installing both updates independently and simultaneously, they continued to fail. This was particularly frustrating for developers using Visual Studio 2005, as the 32-bit version of the redistributable package (KB2538242) was essential for their work.

After some trial and error, a user finally discovered that the problem lay with the VCREDIST.MSI file being used by the 64-bit version. By downloading the install packages directly from Microsoft (VCREDIST_X86.EXE and VCREDIST_X64.EXE), they were able to manually install each update one at a time. However, even this method failed when attempting to install KB2538243.

The reason for this failure became clear after running the System File Checker (SFC) three times and attaching the last log file as an attachment. The issue was identified as a security problem with MFC applications, which led to DLL planting due to MFC not specifying the full path to system/localization DLLs.

To resolve this issue, users were advised to run the Tweak Windows Repair Kit version 3.4.2 and then attempt to install KB2538243 again. Unfortunately, even this method failed initially, with the update continuing to try to install but ultimately failing every time.

In conclusion, installing updates can be a complex process, especially when dealing with Microsoft Visual C++. The issue described in this article highlights the importance of manual installation and troubleshooting steps to resolve problems that may arise during the installation process. By following these steps and seeking help from online resources, users can overcome even the most challenging issues and keep their systems up-to-date and secure.
