Apache won t start in wamp

Question

I have been googling for the past few hours but I simply can t get my apache on wamp to start  My skype isn t running  and the test port 80 shows it isn t being used by anything  Before this happened  I was trying to add a new vhost  but now I have reverted back all of the files where I made changes  Anyway to debug why apache won t start   Clicking on start resume service for apache doesn t show any errors either   Also just in case   I am running Win7 64bit

That is what I did and it helped me to find out what my Apache-PHP needed:

C:\Users\Admin>cd C:\wamp\bin\apache\apache2.4.9\bin

C:\wamp\bin\apache\apache2.4.9\bin>httpd -t
Syntax OK

C:\wamp\bin\apache\apache2.4.9\bin>httpd -k start
[Thu Apr 23 14:14:52.150189 2015] [mpm_winnt:error] [pid 3184:tid 112] 
(OS 2)The system cannot find the file specified.  : AH00436: 
No installed service named "Apache2.4".

C:\wamp\bin\apache\apache2.4.9\bin>

The most simple solution:

Uninstall and reinstall WAMP (do not even try to set it up on top of existing installation - it would not help)

P.S.

If you wonder how did I get to this situation, here is the answer: I was trying to install WAMP and it throws me an error in the middle of installation saying:

httpd.exe - System Error

The program can't start because MSVCR110.dll is missing from your computer. 
Try reinstalling the program to fix this problem.

OK

I got and installed Microsoft Visual C++ 2012 Redistributable from here http://www.microsoft.com/en-us/download/details.aspx?id=30679#

And it gave me the "dll" and the MYSQL started working, but not Apache. To make Apache to work I uninstalled and reinstalled WAMP.

If you have an issue in the httpd conf or any files included by it there are a couple of ways to find out what the problem is  First look at your Windows Event Viewer  Click on the Windows link in the  menu on the left  and then submenu Applications  Look for messages from Apache with the red error icon   Secondly  open a command window  then CD into  wamp bin apache apache2 x y bin  replace x y with your actual version  Now you can run this command to get Apache httpd  to vaidate the httpd conf file   httpd exe -t   This should give errors with line numbers related to the http conf file  It stops on the first error  so you will have to keep running it and fixing the error and then run it again until it gives the all OK message

I was having the same problem  the mysql service was starting but not the apache service  the main problem about that is one of your virtual hosts isn t config  correctly  all i did was deleted the virtual host that i created  D  wamp bin apache apache2 4 23 conf extra httpd-vhosts  restarted all services apache service started working correctly and so i just went to localhost and added a virtual host automatically and so it worked

If Apache is installed as a Windows service  any errors will show up in the Windows System event log   To view the System event log  navigate to Windows Administrative Tools- Event Viewer and open the System log in the Windows Logs folder   Or  you can see the same errors by running httpd exe at the command line  In my case  httpd exe is located here  C  Bitnami wampstack-5 6 26-2 apache2 bin    If there is a problem with starting Apache  most likely the problem can be fixed by editing the httpd conf file located in the  apache2 conf folder  As already suggested  you can check the syntax of the httpd conf file by running httpd exe -t at the command line     I found that the I had to      Change SetEnv PATH  C  Bitnami wampstack-5 6 26-2 apache2 bin   PATH   in httpd conf   to     SetEnv PATH  C  Bitnami wampstack-5 6 26-2 apache2 bin  PATH
