Showing Error opening of WAMP server - php

Question

I have installed WampServer 2.2 on Windows 8.1.
When I try to start WampServer, it shows the following error:
The program can't start because MVSCR110.dll is missing from your computer.
How can I fix this?

Answer 1

MVSCR110.dll references to the Visual C++ 2012 Redistributable, of which you do not have.
The Visual C++ 2012 Redistributable is required for Apache to run. The reason why your Wamp installation is not going online is because Apache is unable to start.
A forum post on the WAMP Server forums deals with this problem with an earlier version of Wamp, to quote:
For Windows 32 : Be sure that you have installed the Visual C++ 2012
SP1 Redistributable Package x86 : VC12 SP1 vcredist_x86.exe
For Windows 64 : Be sure that you have installed the Visual C++ 2012
SP1 Redistributable Package x64 : VC12 SP1 vcredist_x64.exe
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.
Some users have also said that installing the Redistributable for their processor type isn't enough, so it may be a good idea to install both x64 and x86 versions.
WampServer versions b and later require the VC++ 2012 version, which can be downloaded here.

Answer 2

As far as I remember Windows 8.1 comes (out of the box, so to speak) with only one of Microsofts Visual C++ runtimes installed.
It seems a little odd that you are getting the message you claim if you are in fact using WAMPServer 2.2(a,c,d,or e)
The program can't start because MVSCR110.dll is missing from your
computer.
As as far as I am aware nothing delivered by any of the WAMPServer 2.2 releases i.e. 2.2a, 2.2c, 2.2d, 2.2e were compiled with MSVC 2012. In fact as stated on the download pages on SourceForge
Attention : All the components of the v2.2 WampServer stack have been compiled with VC9 version of Microsoft compiler. Earlier versions of Wampserver have been made with VC6 version of Microsoft compiler. So, You can't mix components of 2.2 stack with previous version of Wampserver Stack components. If you do it you will get an instable Wampserver.
However, if that is in fact the error you are getting after installing WAMPServer 2.2, then that message is saying that you need to install the MSVC 2012 runtime library.
Which can be downloaded from here.
You will also need to make sure that you have the MSVC 2008 runtime library installed as well, as wampmanager.exe is an old program as has not needed to be recompiled for a while now which can be downloaded from here
This runtime will also be required to run Apache and MySQL executables if you did in fact install WAMPServer 2.2.something
Oh and if you are using a 64bit WAMPServer, you will need to download and install the 32bit AND the 64bit version of the MSVC 2008 runtime library, as wampmanager.exe is a 32bit program even if you have installed the 64bit version of WAMPServer and of course the Apache and MySQL will need the 64bit libraries.
If this does not fix your issue, then have a look at the Windows Event Log
Windows Key + R to launch the run dialog then enter eventvwr.exe and press the OK button
- On the left side of the windows click 'Windows Logs -> Applications'
- Look for the names 'Apache' or 'MySQL' in the 'Source' column which have a error symbol in the first column.
The error messages sent here are normally very descriptive and should at least point you in the right direction to solving your problem.

Answer 3

when you migrate to windows 8.1, MVSCR110.dll is outdated. then, it should be updated and installed into your PC again.
