I've downloaded WAMP and it comes up with an error message when I try to open the programme. "The program can't start because VCRUNTIME140.dll is missing from your computer. Try reinstalling the program to fix this problem". The first time this happened I uninstalled and then did another install. Same error message. What can I do please?

You are one of the "crazy clicks" that click on everything that moves without even reading at least two words of the explanations given before starting the installation.

--- 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 and VC14
See --- Visual C++ Packages below.
--- Do not install Wampserver OVER an existing version, follow the advice:
- Install a new version of Wampserver: []
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:[]
- Disable IIS
Item No. 08 of the Wampserver TROUBLESHOOTING TIPS:[]
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
-- VC9 Packages (Visual C++ 2008 SP1)
-- VC10 Packages (Visual C++ 2010 SP1)
-- VC11 Packages (Visual C++ 2012 Update 4)
The two files VSU4\vcredist_x86.exe and VSU4\vcredist_x64.exe to be download are on the same page: []

The two files VSU4\vcredist_x86.exe and VSU4\vcredist_x64.exe to be download are on the same page: []

The two files vcredist_x86.exe and vcredist_x64.exe to be download are on the same page:
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.
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 [] section Visual C++ Redistribuable Packages is up to date.
This is item number 20 of TROUBLESHOOTING TIPS
