wamp doesn't start because MSVCR110.dll is missing

Question

When I start Wampserver 3.0.0 I get the message "wamp can't start because MSVCR110.dll is missing", this is despite my having downloaded vcredist_x64 (Microsoft Visual C++ 2012 Redistributable x64) from Microsoft site for my 64 bit machine and having installed it. Any suggestion as to what else I should do?

Answer 1

You have not followed the prerequisites that are displayed BEFORE installation begins. You have not read and validated Next. Yet the text is very explicit

--- 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 Even if you think you are up to date, install each package as administrator and if message "Already installed", validate Repair.

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

If you have a 64-bit Windows, you must install both 32 and 64bit versions, even if you do not use Wampserver 64 bit.
