The <code>MSVCR100.dll</code> file is part of the <code>Microsoft Visual C++</code>, redistributables. You can install them and see if this solves your problem. After you install the above check if your wamp installation is correctly setup. Search for "my wamp icon stays orange" posts.

UPDATE 2019

<blockquote>
 Wampserver 3 requires Visual C++ Redistributable for Visual Studio 2012 Update 4
 You can download it at:
 <a href="https://www.microsoft.com/en-us/download/details.aspx?id=30679" rel="noreferrer">https://www.microsoft.com/en-us/download/details.aspx?id=30679</a>
 There you can select the x86 or x64 version depending on your system
</blockquote>

<a href="http://forum.wampserver.com/read.php?2,123608" rel="noreferrer">This article</a> on the WampServer forums shows all the Microsoft Visual C++ runtime libraries you need to have installed on your system for each version of WampServer. To quote:

<blockquote>
 For Windows 32 : Be sure that you have installed the Visual C++ 2010
 SP1 Redistributable Package x86 : VC10 SP1 vcredist_x86.exe
 
 <a href="http://www.microsoft.com/download/en/details.aspx?id=8328" rel="noreferrer">http://www.microsoft.com/download/en/details.aspx?id=8328</a> 
 
 For Windows 64 : Be sure that you have installed the Visual C++ 2010
 SP1 Redistributable Package x64 : VC10 SP1 vcredist_x64.exe
 
 <a href="http://www.microsoft.com/download/en/details.aspx?id=13523" rel="noreferrer">http://www.microsoft.com/download/en/details.aspx?id=13523</a> 
 
 Apache will not run without this component
 
 In fact if you are running the 64bit Windows it is a good idea to install all the 32bit libraries as well as the 64bit ones. After all 64bit windows runs 64 and 32 bit code. You will probably find you need at least one of the 32bit runtimes for some app/utility you will install at some point.
</blockquote>

UPDATE

If you are running WAMPServer 2.5 you also need the VC11 redist. Visual C++ Redistributable for Visual Studio 2012 

29.08.2014 with WAMP 2.5
I agree that VC11 is needed and it is not a bad idea to have previous distributions installed. It will be needed by other application. I am not sure if you need bit 32 version

UPDATE Aug. 3rd 2016

As I was informed by Fred -ii- (many thanks by the way) the link for the post in the wamp forums doesn't work anymore. Since I could not find the original link you can try <a href="http://forum.wampserver.com/read.php?2,138295" rel="noreferrer">http://forum.wampserver.com/read.php?2,138295</a>.

Most of the time you will have to install both x86 and x64 !

They are the Visual C++ 2010 SP1 Redistributable Package 

(it happened to me when installing MySQL Workbench)

For me none of the above answers worked so I am adding what worked for me. I first installed the files mentioned in the accepted answer and when that not worked, I downloaded files from <a href="http://www.microsoft.com/en-us/download/details.aspx?id=30679" rel="noreferrer">this</a> link and it started working.

So I think 2012 distribution is also needed (I am using window7 home basic 64 FYI).

Issue was at same OS (Win7 HB x64) as in <a href="https://stackoverflow.com/a/23845445/3472757">this answer</a>. I used gaurav's advice and successfully started WAMP. 

I wanted to add that you don't need Visual C++ 2010 versions when using 2012 version (at least in this case).

Edit: Since I have encountered the same issue again, I have noticed that my previous solution did not work; as well as any other solution posted here. I am using Windows 7 Professional (64 Bit).

This time, I have placed the 'MSVCR100.dll'file (downloaded as a ZIP, then extracted onto Desktop and then copied) into a C:\Windows folder <a href="http://www.dll-files.com/dllindex/dll-files.shtml?msvcr110" rel="nofollow">http://www.dll-files.com/dllindex/dll-files.shtml?msvcr110</a>

and then installer WAMP Server, 64BIT.
<a href="http://sourceforge.net/projects/wampserver/" rel="nofollow">http://sourceforge.net/projects/wampserver/</a> 

Then, I have downloaded and installed:
<a href="http://www.microsoft.com/en-us/download/confirmation.aspx?id=30679" rel="nofollow">http://www.microsoft.com/en-us/download/confirmation.aspx?id=30679</a>

filename: vcredist_x64.exe

I have only tested it with the PHP from a command-prompt, since I do everything else on a server and not a local-host. 

Although it works for what I need to use it

Running:

<blockquote>
 php
 gives Failed loading php_xdebug-2.2.5-5.5-vc11.dll
 
 php -v
 -WORKS!
</blockquote>

Please let me know if this worked for you or not or if there is something else I need to do to improve the fix.

If you are using WampServer 2.5 on a 64bit Windows
You will need both the 32bit and 64bit versions of this runtime.

Today I installed Wamp server 3.0.6 (x64) on a Windows 10 machine with VS2017 installed. I had many Visual C++ Redistributable Packages installed, but not the 2012 one. Then I installed it and now I can run the Wamp server. You can find a download link <a href="https://www.howisolve.com/msvcr110-dll-is-missing/" rel="noreferrer">here</a>.

I encountered this problem when my operating system was in French, and I was installing Wampserver in English. 

I am pretty sure that Microsoft Redistributable packages were installed since I was already working with Visual Studio. I think the issue may have been because of changes in path names with different languages. However, when I installed wampserver in French, everything worked perfectly.

When installing Wamperserver 3 on windows 10, it now gives a nice big warning during the install telling you it won't work unless you install many of these packages.

It worked for me after I followed the instructions and then restart the computer and reinstalled.

<blockquote>
 --- Installation of Wampserver --- BEFORE proceeding with the installation of Wampserver, you must ensure that certain elements are
 installed on your system, otherwise Wampserver will absolutely not
 run, and in addition, the installation will be faulty and you need to
 remove Wampserver BEFORE installing the elements that were missing.
 Make sure you are "up to date" in the redistributable packages VC9,
 VC10, VC11, VC13 , VC14 and VC15 See --- Visual C++ Packages below.
 
 --- Do not install Wampserver OVER an existing version, follow the advice:
 - Install a new version of Wampserver: <a href="http://forum.wampserver.com/read.php?2,123606" rel="nofollow noreferrer">http://forum.wampserver.com/read.php?2,123606</a> If you install
 Wampserver over an existing version, not only it will not work, but
 you risk losing your existing databases.
 
 --- Install Wampserver in a folder at the root of a disk, for example C:\wamp or D:\wamp. Take an installation path that does not include
 spaces or diacritics; Therefore, no installation in c: \ Program
 Files\ or C: \ Program Files (x86\ We must BEFORE installing, disable
 or close some applications:
 - Close Skype or force not to use port 80 Item No. 04 of the Wampserver TROUBLESHOOTING
 TIPS:<a href="http://forum.wampserver.com/read.php?2,134915" rel="nofollow noreferrer">http://forum.wampserver.com/read.php?2,134915</a>
 - Disable IIS Item No. 08 of the Wampserver TROUBLESHOOTING TIPS:<a href="http://forum.wampserver.com/read.php?2,134915" rel="nofollow noreferrer">http://forum.wampserver.com/read.php?2,134915</a> If these
 prerequisites are not in place, Press the Cancel button to cancel the
 installation, then apply the prerequisites and restart the
 installation. This program requires Administrator privileges to
 function properly. It will be launched with the "Run as administrator"
 option. If you do not want a program to have this option, cancel the
 installation.
 
 --- Visual C++ Packages --- The MSVC runtime libraries VC9, VC10, VC11 are required for Wampserver 2.4, 2.5 and 3.0, even if you use only
 Apache and PHP versions with VC11. Runtimes VC13, VC14 is required for
 PHP 7 and Apache 2.4.17 or more

 -- VC14 Packages (Visual C++ 2015 Update 3) Supersedes by VC15

 backward compatible to VC2015 (VC14). That means, a VC14 module can be
 used inside a VC15 binary. Because this compatibility the version
 number of the Redistributable is 14.1x.xx and after you install the
 Redistributable VC2017, VC2015 is removed but you can still use VC14.
 
 If you have a 64-bit Windows, you must install both 32 and 64bit
 versions of each VisualC++ package, even if you do not use Wampserver
 64 bit To verify that all VC ++ packages are installed and with the
 latest versions, you can use the tool:
 <a href="http://wampserver.aviatechno.net/files/tools/check_vcredist.exe" rel="nofollow noreferrer">http://wampserver.aviatechno.net/files/tools/check_vcredist.exe</a> and
 you will find all the packages on <a href="http://wampserver.aviatechno.net/" rel="nofollow noreferrer">http://wampserver.aviatechno.net/</a> in
 section Visual C++ Redistribuable Packages You must install each
 package "as an administrator", so right-click the exe file and then
 run as Administrator. Do not use a previously loaded tool. Make a new
 download to make sure you are using the correct version.
 
 Warning: Sometimes Microsoft may update the VC ++ package by breaking
 the download links and without redirect to the new. If the case
 happens to you, remember that item number 20 below will be updated and
 the page <a href="http://wampserver.aviatechno.net/" rel="nofollow noreferrer">http://wampserver.aviatechno.net/</a> section Visual C++
 Redistribuable Packages is up to date. This is item number 20 of

When I tried to install WAMP, that popped up the following alert,
<img src="https://i.stack.imgur.com/C1dkH.png" alt="MSVCR100.dll is missing">

I clicked OK, it continued to install WAMP. When I start, the WAMP logo is always 'yellow'. It isn't turning 'green', meaning there's something wrong. What exactly is the <code>MSVCR100.dll</code> file? How do I obtain it and fix this error?

WAMP shows error 'MSVCR100.dll' is missing when install

Visual Studio

数据库

服务器

Windows

MySQL

当我尝试安装WAMP时，弹出了以下警告：​我点击OK，它会继续安装WAMP。当我开始的时候，WAMP的标志总是“黄色”的。它没有变成“绿色”，这意味着有什么问题。MSVCR100.dll文件到底是什么？如何获取并修复此错误？
