Are you running a piece of software and suddenly get the message: “This program can’t be started because the vcruntime140.dll is missing from your computer”? Don’t worry, this is not a system poison or a serious failure, but a common problem of missing dynamically linked libraries (DLLs) files. This article will explain the role of vcruntime140.dll in detail and provide simple and effective solutions to help you quickly restore normal program operation.
1. What exactly is vcruntime140.dll?
vcruntime140.dll is one of the core components in Microsoft Visual C++ Redistributable for Visual Studio 2015-2022 and is part of the C++ runtime library. It provides underlying support for a large number of applications and games developed using the C++ language and is an essential file for the smooth operation of programs.
Specifically, the file mainly undertakes the following functions:
- The helper calls the necessary VC runtime functions at startup.
- Implement key system operations such as memory management and exception handling.
- Ensure that programs written in C++ run stably on Windows systems.
Once this file is missing from the system, like an engine missing critical parts, many programs will not load properly.
2. Why is vcruntime140.dll lost?
It was obviously still used normally before, but why did it suddenly get an error? There are usually several reasons for the missing document:
1. The necessary running library is not installed
Some software does not automatically install the required Visual C++ runtime during the installation process, resulting in the lack of critical files such as vcruntime140.dll.
2. Deleted by mistake by the cleaning tool
System optimization or junk cleaning software may mistakenly identify the file as redundant and delete it, causing the program to fail.
3. File corruption or version conflict
System updates, software upgrades, or incompatible installation packages may cause the original runtime files to become corrupted or invalid, making them unrecognizable by the program.
