WAMP won't turn green. And the VCRUNTIME140.dll error

WAMP won't turn green. It was working fine a couple of weeks ago. When looking at other answers on this topic, a lot said to install services in Apache.

When I do this, I get an error code stating:

> "The program can't start because VCRUNTIME140.dll is missing from your computer. Try reinstalling the program to fix the problem."

As Oriol said, you need the following redistributables before installing WAMP.

From the readme.txt

The following packages (VC9, VC10, VC11) are imperatively required to Wampserver 2.4, 2.5 and 3.0, even if you use only Apache and PHP versions VC11 and VC14 is required for PHP 7 and Apache 2.4.17

Quite simply:

1. Uninstall wampserver
2. Install Visual C++ Redistributable for Visual Studio 2015
3. Install wampserver

You need to install some Visual C++ packages BEFORE installing WAMP (if you have installed then you must uninstall and reinstall).

You need: VC9, VC10, VC11, VC13 and VC14

In readme.txt of wampserver 3 (on SourceForge) you can find the links.

Be careful! If you use a 64-bit OS you need to install both versions of each package.

> VCRUNTIME140.dll error

This error means you don't have required Visual C++ packages installed in your computer. If you have installed wampserver then firstly uninstall wampserver.

Download the VC packages

Download all these VC packages and install all of them. You should install both 64 bit and 32 bit version.

install packages with admin priviliges
Right click->Run as Administrator

install wampserver again
After you installed both 64bits and 32 bits version of VC packages then install wampserver again.

I had the same problem, and I solved it by installing :

• Redistribuable Visual C++ pour Visual Studio 2012 Update 4 (6.9 MB)
• Redistributable Visual C++ pour Visual Studio 2015 Update 1 (14.1 MB)

NB : 64 bit installation was enough, I had to uninstall / reinstall Wamp after that

Since you already had a running version of WAMP and it stopped working, you probably had VCRUNTIME140.dll already installed. In that case:

1. Open Programs and Features
2. Right-click on the respective Microsoft Visual C++ 20xx Redistributable installers and choose "Change"
3. Choose "Repair". Do this for both x86 and x64

This did the trick for me.

After lots and lots of installing and uninstalling for a whole day and trying every packages for every answers in here, the only thing that worked for me was:

1. Uninstall Wamp and reboot
2. installing Visual Studio 2017 Community edition and choose "Web development" and check all of the options in the right site. Here's a screenshot:

This somehow install something that is needed for Wamp as well.

3. install Wamp, and you should be all good.
