阅读11分钟msvcp120.dll 丢失多半是 VC2013 运行库缺失、杀毒误删或系统文件损坏。优先安装 VC2013 运行库，再从杀毒隔离区还原，接着用 sfc /scannow 修复，最后再考虑手动拷贝 DLL，以下方法在 Windows 10/11 实测可用。
多数情况是运行库组件没装全或被杀毒软件隔离，硬件本身没有坏，不用急着重装系统或送修。
适用系统：Windows 10/11；最后更新：2026-08-31。
为什么一直提示 msvcp120.dll 丢失？
报错原文通常是：“无法启动此程序，因为计算机中丢失 msvcp120.dll。尝试重新安装该程序以解决此问题。” 这个 dll 的默认位置是 C:\Windows\System32\msvcp120.dll 和 C:\Windows\SysWOW64\msvcp120.dll，文件不见了，依赖它的软件就会在启动时中断。常见触发场景包括 Adobe Premiere、Photoshop、部分国产软件和 Steam 游戏。

先判断自己属于哪一类：是运行库没装、被安全软件隔离，还是系统文件损坏。对症处理比反复重装软件省事得多。如果报错出现在刚安装某款软件之后，优先考虑重新安装该软件。
方法1 安装VC2013运行库
msvcp120.dll 属于 VC++ 2013 运行库，装上对应版本能直接补全文件。VC2013 运行库分 x86 和 x64 两个安装包，x86 给 32 位程序用，x64 给 64 位程序用，建议两个都装。这个报错常见于 Adobe 软件、游戏和部分国产软件，装完重启就能生效。

操作步骤
- 打开浏览器访问微软官网，在搜索框输入“Visual C++ 2013 Redistributable”，找到官方下载页面。
- 在页面里下载 vcredist_x86.exe 和 vcredist_x64.exe 两个安装包，32 位和 64 位版本都装更稳妥。
- 右键安装包，选择“以管理员身份运行”，勾选同意协议，等待安装进度走完。
- 重启电脑后重新打开原软件，看是否还提示 msvcp120.dll 丢失。
方法2 从杀毒隔离区恢复msvcp120.dll
杀毒软件可能把 dll 当风险文件隔离了，还原后再加排除项即可。Windows 安全中心的隔离区在“保护历史记录”里，第三方杀毒软件也有类似记录。如果装好运行库仍提示丢失，多半就是文件被隔离或误删。

操作步骤
- 打开 Windows 安全中心，进入“病毒和威胁防护”，点击“保护历史记录”。
- 筛选“已隔离项目”，按时间找到 msvcp120.dll 相关条目。
- 点击该条目的“操作”按钮，选择“还原”。
- 在“排除项”里添加软件安装目录，避免运行库文件被再次隔离。
用「软领DLL系统修复」更省事
软领DLL系统修复的“dll修复”功能可以一键扫描系统里缺失或损坏的 DLL 文件，包括 msvcp120.dll。扫描后直接补全对应版本，不用自己分辨 32 位还是 64 位，装完重启软件就能正常打开。对不熟悉命令行的用户来说，这一项能省去手动 copy 的步骤。
“运行库修复”会批量安装 VC++ 2013 这类常见运行库组件。msvcp120.dll 正是 VC2013 运行库的一部分，把运行库补全后，像缺少 msvcp120.dll、缺少 msvcp140.dll 这类报错会一起解决。它适合一次处理多个软件轮流报 DLL 缺失的情况。
软领是知名国产软件品牌，20 年技术沉淀、服务千万用户。官网 wyouhua.com 直接下载，安装没有捆绑勾选项。
拿不准时，软件里点客服按钮能联系真人工程师，复杂情况可以远程协助。
方法3 用sfc /scannow修复系统文件
系统文件损坏也会导致 dll 找不到，sfc 能扫描并还原受保护的系统文件。运行 sfc 前建议先确认 C 盘有足够剩余空间，避免扫描中断。如果 sfc 本身失败，再用 DISM 修复系统映像。

操作步骤
- 按 Win+R 打开运行窗口，输入 cmd，再按 Ctrl+Shift+Enter 以管理员身份打开命令提示符。
- 输入 sfc /scannow 并回车，等待扫描完成，中间不要关机。
- 如果提示“Windows 资源保护无法执行请求的操作”，先执行 DISM /Online /Cleanup-Image /RestoreHealth，再重新运行 sfc。
- 修复完成后重启电脑，再次运行 sfc /scannow 确认没有报错。
方法4 手动拷贝msvcp120.dll到系统目录
前几步无效时，可从正常电脑复制对应版本的 dll 到系统目录，作为兜底。手动拷贝前先确认软件是 32 位还是 64 位，放错目录仍然会报错。从别的电脑拷贝时，尽量选同版本 Windows，避免 dll 版本不匹配。

操作步骤
- 找一台同版本 Windows 且运行正常的电脑，打开 C:\Windows\System32 和 C:\Windows\SysWOW64 文件夹。
- 确认自己软件的位数，64 位软件从 System32 里复制 msvcp120.dll，32 位软件从 SysWOW64 里复制，拷到 U 盘。
- 回到出问题的电脑，以管理员身份打开命令提示符，假设 U 盘盘符是 E，执行 copy /Y E:\msvcp120.dll C:\Windows\System32\。
- 如果软件是 32 位，再执行一次 copy /Y E:\msvcp120.dll C:\Windows\SysWOW64\，然后重启电脑。
常见问题
msvcp120.dll丢失怎么修复？
先装 VC2013 运行库，再从杀毒隔离区还原，之后运行 sfc /scannow，最后再手动拷贝 dll 到 System32 或 SysWOW64。多数人第一步就能解决，注意 x86 和 x64 都要装。
电脑提示无法启动此程序，因为计算机中丢失msvcp120.dll怎么办？
这条报错说明软件依赖的 VC2013 运行库文件缺失。先下载 vcredist_x86.exe 和 vcredist_x64.exe 并安装，如果还报错再看杀毒隔离区。
装完VC2013运行库还是提示msvcp120.dll丢失，怎么回事？
可能是杀毒把 dll 隔离了，或系统文件损坏。到 Windows 安全中心的“保护历史记录”里还原，再运行 sfc /scannow 检查。
msvcp120.dll是微软VC2013运行库吗？
是。msvcp120.dll 是 Visual C++ 2013 Redistributable 的运行时组件，许多软件依赖它，所以装对应版本运行库就能补全。
msvcp120.dll下载后放到哪个文件夹？
32 位软件放 C:\Windows\SysWOW64，64 位软件放 C:\Windows\System32。但更推荐先装 VC2013 运行库，系统会自动放到正确位置。
