Do you keep receiving a “program can’t start because MSVCR120.dll is missing” error while attempting to launch an application in Windows 10? Typically, the reason for that lies with a corrupt or missing Visual C++ Redistributable installation.
The Visual C++ Redistributable package contains crucial runtime components for programs built using C++ to work correctly. Although there are many versions of the package, the MSVCR120.dll file is specific to the Visual C++ 2013 Redistributable.
The list of troubleshooting methods that follow should help you fix the MSVCR120.dll missing error on Windows.
1. Install Microsoft Visual C++ 2013 Redistributable
Programs that depend on the Visual C++ 2013 Redistributable will automatically add the package’s relevant components to your computer during installation.
To confirm, head over to Start 开始 > 个人设置 > 应用 > 应用程式和功能. Then, scroll down and check for Microsoft Visual C ++ 2013 Redistributable. You should see separate listings—(x64) and (x86)—of the same package unless you run a 32-bit version of Windows.
If you can’t locate the Visual C++ 2013 Redistributable, you must install it manually. Visit the Visual C++ Redistributable Packages for Visual Studio 2013 page at the official Microsoft website, select 下载,然后抓住 vredist_x64.exe 和 vcredist_x86.exe 安装人员。
Follow by running both installers one after the other to install the Visual C++ 2013 Redistributable. Next, reboot your computer and check if the “MSVCR120.dll is missing” error recurs.
Alternatively, you can use the Visual C++ 2013 Redistributable installers from the installation source of the program causing the ‘msvcr120.dll is missing’ error. They should be present within a folder labeled 录像机.
2. Repair Microsoft Visual C++ 2013 Redistributable
If the Microsoft Visual C++ 2013 Redistributable is present on your computer, you must repair it to rule out issues caused by file corruption.
从选择开始 Microsoft Visual C++ 2013 可再发行组件 (x64) from within the Apps section of the Settings app and choose 修改.
On the Modify Setup wizard that shows up, select 维修 and wait for it to repair the installation. Then, repeat what you just did for Microsoft Visual C++ 2013 可再发行组件 (x86).
If you encounter any issues while repairing the Visual C++ 2013 Redistributable, use the 卸载 option to remove both packages from your computer. Next, download new installers and use them to reinstall the Visual C++ 2013 Redistributable from scratch.
3. Copy MSVCR120.dll to Program Folder
In some instances, copying the MSVCR120.dll file to a problematic program’s installation directory can help eliminate the “MSVCR120.dll is missing” error.
You should find a 64-bit and a 32-bit version of the MSVCR120.dll file located within the following directories:
- 本地磁盘(C :) > Windows > System32 — 64-bit version
- 本地磁盘(C :) > Windows > SysWOW64 — 32-bit version
Depending on the program’s version, copy and paste the MSVCR120.dll file into the root of its installation folder. Programs located under the 程序文件(x86) folder, for example, run in 32-bit, so you must use the MSVCR120.dll file from SysWOW64.
请注意: If you use a 32-bit version of Windows 10, you must use the MSVCR120.dll file from the System32 文件夹中。
4. Repair or Re-install Program
If you still keep receiving the “MSVCR120.dll is missing” error on your computer, try repairing or reinstalling the program that causes it to show up. Hopefully, that should take care of issues stopping it from working with the Visual C++ 2013 Redistributable.
在MyCAD中点击 软件更新 Start 开始 > 个人设置 > 应用. Then, select the program and pick 修改 to repair it. If the option appears grayed out, remove the program and reinstall it instead.
5. Update Program
It’s also a good idea to update the program. Obtain the latest version of the application installer—via the developer’s website, for example—and use it to update or reinstall the program.
6.安装Windows 10更新
The latest Windows 10 updates contain fewer bugs and glitches that could prevent programs from locating the Visual C++ 2013 Redistributable runtime components. If you haven’t updated your computer in a while, you should do that now.
打开 Start 开始 菜单并转到 个人设置 > 更新与安全。 然后,选择 检查更新 并选择 安装软件 to apply any updates.
7.运行系统文件检查器
Although the Visual C++ 2013 Redistributable isn’t a part of Windows 10, you should check and fix any system-related errors using the System File Checker regardless.
媒体 Windows+S to open Windows Search, type CMD,然后选择 以管理员身份运行“. Then, type SFC / SCANNOW into the elevated Command Prompt console and press 输入.
An SFC scan usually takes several minutes to complete. If it appears to get stuck, do be patient, and it should start moving again after a while.
Additionally, you can run a DISM(部署映像服务和管理)扫描 并使用 检查磁盘 (chkdsk) to fix additional errors on your computer.
8. Scan for Computer Viruses
No luck yet? You should remove the possibility of a malware infection by scanning for computer viruses.
Try using Windows 10’s native Windows Security tool. You can bring it up by selecting the Windows安全 icon on the system tray. Once it shows up, select 病毒和威胁防护,选择 扫描选项, 切换到 全扫描,并选择 Scan 扫描.
If Windows Security fails to detect anything, you should continue scanning with a dedicated malware removal tool. The free version of 的Malwarebytes is an excellent choice and does an outstanding job at ridding your computer of viruses.
失物招领
In most cases, installing or repairing the Visual C++ 2013 Redistributable should permanently take care of the “MSVCR120.dll is missing” issue.
If you continue to receive the error despite working your way through the rest of the suggestions, you should consider resetting Windows 10 to factory defaults.
