Windows 10 might be the latest version of Windows, but it still suffers from some old problems. One of the common problems that other versions of Windows have is the side-by-side configuration error.

This error has managed to find its way to Windows 10 as well, but worry not, there’s a way how to fix this error. What does side-by-side configuration error mean?

This error appears when you try to install or update certain software and is usually caused by a conflict between the software that you’re trying to update/install and files in the C++ runtime libraries.

These C++ libraries are part of the Windows operating system, and often they get updated when you install Microsoft software or sometimes third party software.

It doesn’t work at all. When I try to uninstall Visual C++, side by side configuration error is appear, and uninstall process is aborted

I got the same problem. After the Anniversary Update all the C++ installs are corrupt. I can’t run a lot of programs, like Office 2013, due to the side-by-side error. I can’t repair or uninstall the C++ installs. Thanks Microsoft for breaking your operating system.
