阅读11分钟电脑提示 msvcp140.dll 丢失，多数是 Visual C++ 运行库没装好或被误删造成的，和硬件无关，也不必急着重装系统。这个文件属于微软 Visual C++ 2015-2022 运行库，很多游戏和软件启动时都要调用它，按下面从易到难的顺序处理、修好即停即可，方法在 Windows 10/11 实测可用。
适用系统：Windows 10/11；最后更新：2026-07-17。
msvcp140.dll丢失是什么情况
启动某个游戏或软件时，屏幕上弹出“无法启动此程序，因为计算机中丢失 msvcp140.dll”或“找不到 msvcp140.dll”的提示，程序随即打不开。有时还会伴随错误代码 0xc000007b、0x7e，或提示“应用程序无法正常启动”。
msvcp140.dll 是微软 Visual C++ 2015-2022 可再发行组件里的一个核心库文件，正常时位于 C:\Windows\System32 或 C:\Windows\SysWOW64。它丢失通常和硬件无关，根源多在运行库没装、被杀毒软件清掉，或被旧版本覆盖。

先根据报错场景和错误码判断缺的是哪一类运行库，再对照下面的顺序逐条处理，避免盲目重装系统。
方法1 用系统文件检查工具扫描修复
系统自带的 sfc 和 DISM 能扫描并补回被破坏的系统级运行库文件，这是最省事的第一步。
操作步骤
- 右键开始菜单，选择“终端(管理员)”或“命令提示符(管理员)”。
- 输入 sfc /scannow 并回车，等待扫描到 100%，它会自动修复找到的系统文件。
- 接着输入 DISM /Online /Cleanup-Image /RestoreHealth 并回车，联网补齐损坏的组件。
- 两条命令都跑完后重启电脑，再打开刚才报错的程序看是否恢复。
方法2 重新安装Visual C++运行库
msvcp140.dll 由 Visual C++ 2015-2022 运行库提供，把这套运行库重新装一遍最能对症。
操作步骤
- 打开微软官网，搜索“Visual C++ Redistributable”进入下载页面。
- 下载 vc_redist.x64.exe（64 位）和 vc_redist.x86.exe（32 位）两个安装包。
- 先运行 x64 版本，勾选同意后点“安装”，装完再运行 x86 版本。
- 两个都装完后重启电脑，让新注册的 msvcp140.dll 生效。

方法3 按系统位数装对应的运行库版本
如果装了运行库仍报错，多半是位数没对上，64 位系统常常要 x64 和 x86 两个版本都装。
操作步骤
- 右键“此电脑”选“属性”，在“系统类型”里确认是 64 位还是 32 位系统。
- 64 位系统把 vc_redist.x64.exe 和 vc_redist.x86.exe 都装上，很多老程序其实是 32 位。
- 确认 C:\Windows\System32 里放 64 位 msvcp140.dll，C:\Windows\SysWOW64 里放 32 位版本。
- 装好后重启，再运行报错的软件确认是否已经找到该文件。

方法4 手动把msvcp140.dll放回系统目录
在运行库暂时装不上的应急情况下，可以从同版本系统的正常电脑复制 msvcp140.dll 放回目录，作为临时办法。
操作步骤
- 从一台同为 Windows 10/11、系统位数相同的电脑，复制 C:\Windows\System32\msvcp140.dll。
- 把文件粘贴到本机的 C:\Windows\System32；若是 32 位程序报错，则放到 C:\Windows\SysWOW64。
- 粘贴完成后重启电脑，让系统重新加载这个库文件。
- 重新打开报错的程序测试，若仍不行说明缺的不止一个文件，回到方法二补装完整运行库。
方法5 用Windows更新补齐运行时组件
部分运行时组件会随 Windows 更新一起下发，把系统更新到最新能补上缺失的依赖。
操作步骤
- 点“开始”→“设置”→“Windows 更新”，点击“检查更新”。
- 把所有可用更新和可选更新都装上，其中包含部分运行库和系统组件。
- 更新过程中可能多次重启，全部装完后再手动重启一次。
- 更新完成后重新运行报错程序，确认 msvcp140.dll 提示是否消失。
方法6 定位并重装报错的软件或游戏
如果只有某一个程序报缺 msvcp140.dll，问题多半在该程序自带的运行库没装好，重装它更直接。
操作步骤
- 先卸载报错的软件或游戏，卸载时勾选清理残留文件。
- 到官方渠道重新下载安装包，安装时留意它会附带安装 Visual C++ 运行库。
- 如果安装目录里有 vcredist 或 redist 文件夹，手动运行里面的运行库安装包。
- 装好后启动程序，多数情况下缺失提示会一并解决。

常见问题
msvcp140.dll是什么文件，为什么很多软件都需要它？
它是微软 Visual C++ 2015-2022 运行库里的 C++ 标准库文件，用 Visual Studio 开发的软件和游戏运行时都要调用它，所以少了它程序就起不来。
装了Visual C++运行库还是提示丢失怎么办？
多半是只装了一个位数，64 位系统要把 x64 和 x86 两个版本都装上，装完重启即可；仍不行再用 sfc /scannow 检查系统文件。
只把msvcp140.dll复制到System32安全吗？
作为应急可以，但单独复制的文件版本未必匹配，容易再报别的错，最稳妥还是装完整的 Visual C++ 运行库。
msvcp140.dll和msvcp140_1.dll、msvcp140_2.dll有什么区别？
它们都属于同一套 VC++ 2015-2022 运行库，后缀数字是微软后续版本追加的库，装最新的运行库会把它们一并补全。
修复后游戏还是打不开，问题出在哪？
可能是游戏自带的运行库损坏或缺别的组件，先重装该游戏并运行它自带的 vcredist，再用软领DLL系统修复扫一遍缺失文件。
