在Windows10 64位系统安装WAMP时遇msvcr120.dll缺失错误，求解决方法

Hey there, I’ve dealt with this exact headache when setting up WAMP on Windows 10 64-bit—total buzzkill, but it’s a straightforward fix once you know the root cause. Let’s get you back on track:

What’s causing this? #

The msvcr120.dll file is part of the Microsoft Visual C++ Redistributable Packages for Visual Studio 2013. WAMP relies on these runtime libraries to run, and if they’re missing or outdated, you’ll get that error pop-up.

Step-by-step fix: #

• First, check your installed programs: Open Control Panel > Programs and Features, and look for any entries named Microsoft Visual C++ 2013 Redistributable (either x86 or x64). If you see them, uninstall them first—sometimes old/corrupted installs cause conflicts.
• Next, grab the official redistributable packages: You need both the x86 and x64 versions (yes, even on 64-bit Windows—some WAMP components depend on 32-bit libraries). Never download standalone .dll files from random sites—they’re often infected or incompatible.
• Install the x86 package first, then the x64 one. Follow the on-screen prompts, and make sure to restart your computer once both are installed.
• After rebooting, fire up the WAMP installer again. The msvcr120.dll error should be gone, and you can proceed with setting up your local server.

Quick troubleshooting if it still happens: #

Double-check that you downloaded the correct WAMP version for your 64-bit system. If you accidentally grabbed the 32-bit WAMP, you might still run into library issues—swap it for the 64-bit installer and repeat the steps above.
