Issue: How to fix MSVCR100.dll missing on not found error in Windows?

I was trying to launch a game I've recently installed, only to get an error message which claims that MSVCR100.dll is missing. How do I fix this?

Solved Answer

Many Windows users may encounter an error message stating that the MSVCR100.dll file is missing or not found. This error typically appears when trying to launch a game, an application, or a certain part of the operating system that requires this DLL file to function properly. When the system is unable to locate the required file or fails to access it due to it being corrupt, this error is triggered, disrupting the normal operation of your software or game.

MSVCR100.dll is an integral component of the Microsoft Visual C++ library, an assembly of pre-written code that software developers can call upon to simplify their coding tasks. “MSVCR” stands for Microsoft Visual C Runtime, while “100” corresponds to the version number, specifically the 2010 version of Visual C++. This DLL file is needed to execute programs written with this particular version of Visual C++.

The cause of the MSVCR100.dll missing or not found error can be multifaceted. The file may have been accidentally deleted, become corrupted, or might not have been installed correctly in the first place. Additionally, some applications may require a specific version of the file, which could lead to compatibility issues if the right version isn't available on your system.

If you're experiencing this error, it's important not to download the DLL file from a website other than Microsoft's, as this can pose a security risk. Instead, the error can typically be resolved by reinstalling the Microsoft Visual C++ Redistributable package, which includes the necessary DLL files.

Details on how to correctly solve this issue are outlined below. Following these instructions should help restore the normal function of your software or game, thus resolving the error. Please remember that, as with any system-level operation, caution should be exercised to prevent any potential damage to your system.
