阅读14分钟vcruntime140.dll缺失修复首选重新安装 Visual C++ 运行库：访问微软官网下载 Visual C++ 2015-2022 Redistributable（x64/x86 各一份），安装后重启，程序即可正常启动。若安装后仍报错，可依次尝试 SFC 系统文件扫描、手动注册 DLL、以及系统还原。
vcruntime140.dll 属于 Microsoft Visual C++ 运行时库，多数报错是运行库未装全、安装包损坏或版本不匹配导致的，硬件本身大多没问题，不必急着重装系统或送修。以下4种方法在 Windows 10/11 实测可用，按从易到难逐个排查，修好即停。
适用系统：Windows 10/11；最后更新：2026-06-22。
vcruntime140.dll缺失是什么情况
打开某款游戏或软件时弹出对话框，提示「由于找不到 vcruntime140.dll，无法继续执行代码。重新安装程序可能会修复此问题」——这条报错意味着该程序依赖的 Microsoft Visual C++ 2015/2017/2019/2022 运行库未正确安装在本机。vcruntime140.dll 存放于 C:\Windows\System32（64位版本）或 C:\Windows\SysWOW64（32位版本），凡是用 Visual C++ 编译的程序都需要它。常见根因包括：运行库从未安装、安装包中途失败、系统更新删除了相关组件、以及卸载某软件时连带移除了共用库。

方法1 重新安装 Visual C++ 运行库（最优先）
绝大多数 vcruntime140.dll 缺失问题，安装对应版本的 Visual C++ Redistributable 后立即解决。微软官方提供免费下载，支持 Windows 10/11。
操作步骤
- 访问微软官网，搜索「Microsoft Visual C++ Redistributable」，进入下载页（或直接搜索 aka.ms/vs/17/release/vc_redist.x64.exe）。
- 同时下载 x64 和 x86 两个版本的安装包（因为 64位系统上的 32位程序需要 x86 运行库）。
- 以管理员身份运行安装包，按提示点击「安装」，完成后重启计算机。
- 重启后重新打开之前报错的程序，确认是否正常启动。
若系统中已有旧版运行库，安装时选择「修复」可直接修复损坏文件而无需卸载旧版。

方法2 运行 SFC 系统文件扫描
若运行库已安装却仍然报错，说明系统文件本身可能损坏——sfc /scannow 会自动检测并还原被篡改的系统 DLL，包括运行库相关文件。
操作步骤
- 按
Win + S搜索「cmd」，右键选择「以管理员身份运行」。 - 输入
sfc /scannow，回车，等待扫描完成（通常需要5-15分钟）。 - 若提示「Windows 资源保护找到了损坏文件并已成功修复」，重启计算机。
- 如果 SFC 无法修复，继续在管理员命令提示符输入
DISM /Online /Cleanup-Image /RestoreHealth，等待完成后再次运行sfc /scannow。
DISM 命令会从 Windows 更新服务器拉取原始文件替换损坏组件，完成后再跑一遍 SFC 成功率更高。
方法3 手动补充 DLL 并注册
在无法联网或运行库安装失败的情况下，可从另一台版本相同的正常 Windows 计算机复制 vcruntime140.dll，手动放入指定目录并用命令行注册。此法为临时方案，优先推荐方法1。
操作步骤
- 从相同系统版本的正常电脑中找到
C:\Windows\System32\vcruntime140.dll（64位），或C:\Windows\SysWOW64\vcruntime140.dll（32位），复制到U盘。 - 将复制的 DLL 粘贴到本机对应目录（
System32或SysWOW64），若提示权限不足，先关闭杀毒软件的文件保护。 - 以管理员身份打开命令提示符，输入
regsvr32 vcruntime140.dll回车，出现「DllRegisterServer 成功」即完成注册。 - 重启计算机，打开报错程序验证。
手动复制的 DLL 版本必须与程序所需版本匹配；若程序同时需要 vcruntime140_1.dll，同步补充该文件到相同目录。

方法4 通过系统还原回滚到报错前状态
若上述方法均未解决，且记得问题是在某次更新或软件安装后出现的，系统还原可以把 Windows 回退到 vcruntime140.dll 存在的时间点，是最彻底的兜底方案。
操作步骤
- 按
Win + S搜索「创建还原点」，点击打开「系统属性」，切换到「系统保护」选项卡。 - 点击「系统还原」，选择「推荐的还原」或「选择不同的还原点」查看可用还原点列表。
- 选择时间在报错出现之前的还原点，点击「下一步」确认受影响的程序。
- 点击「完成」，系统将重启并完成还原（约10-20分钟），完成后验证报错是否消失。
系统还原不会删除个人文件，但还原点创建后安装的软件和驱动会被卸载，操作前建议记录已安装软件清单。如果「系统保护」显示还原功能未启用，说明本机没有还原点，跳过此方法。

常见问题
vcruntime140.dll缺失，重装 Visual C++ 后还是报错怎么办？
先确认安装的是 x64 和 x86 两个版本，32位程序在64位系统上需要 x86 运行库。若仍报错，运行 sfc /scannow 检查系统文件是否损坏，再尝试 DISM 修复后重启。
电脑提示「由于找不到 vcruntime140_1.dll 无法继续执行代码」是同一个问题吗？
vcruntime140_1.dll 是 Visual C++ 2019/2022 运行库的独立组件，与 vcruntime140.dll 并存。修复方法相同——重新安装 Visual C++ 2015-2022 Redistributable（x64/x86）后同时补全两个 DLL。
手动把 vcruntime140.dll 复制到程序目录管用吗？
把 DLL 复制到程序所在目录（而非 System32）可作为临时措施让该程序运行，但不影响其他程序调用，属于治标方案。正确做法是通过运行库安装写入系统目录。
vcruntime140.dll丢失会影响哪些软件？
所有用 Visual C++ 2015 至 2022 编译的程序都受影响，常见的包括：Adobe 系列软件、Skype、多数 PC 游戏（Steam/Epic 平台）、以及部分 Python 程序。报错时一般同时提示程序名称，帮助判断影响范围。
系统还原会删除我的个人文件吗？
不会。系统还原只回滚系统文件和注册表，个人文档、照片、音乐等文件不受影响。但还原点创建后安装的驱动和软件会被卸载，建议还原前记录已安装程序列表。
