WampServer

Hi -

Though I have been in the IT industry for many years I am a total noob to Apache / MySQL / etc., so my apologies (in advance) for my screw-ups.

After sweating - unsuccessfully - with XAMPP I decided to try switching to WampServer.

1. I run Windows 7 Ultimate 64 SP1. My default browser is IE10.
2. I downloaded Wampserver2.4-x64.exe.
3. I installed the C++ 2010 SP1 Redistributable Package x64.
4. I installed WampServer.
5. I confirmed that port 80 - and the local host - were both free.
6. The Windows firewall is off.
7. I installed the WampApache [Apache/2.4.4 (Win64)] & WampMySqld services.
8. However, when I try to start all, the WampApache service fails.
9. The WampMySqld service starts.

The apache_error log reports the following:

[Thu Aug 22 19:09:04.235200 2013] [mpm_winnt:notice] [pid 6172:tid 388] AH00455: Apache/2.4.4 (Win64) PHP/5.4.12 configured -- resuming normal operations

NB: I experienced the same problem with XAMPP.

Any assistance would be appreciated !

Initially check this

Please make sure you have the latest version of all of these Microsoft C++ Redistributable runtime libraries.

The 2008 Redist is used by wampmanager
The 2010 Redist is used by some versions of Apache ( depending on compiler used )
The 2012 Redist is used by some versions of Apache ( depending on compiler used )

FOR WAMP 32bit
Microsoft Visual C++ 2008 SP1 Redistributable Package (x86) [www.microsoft.com]
Microsoft Visual C++ 2010 SP1 Redistributable Package (x86) [www.microsoft.com]

If you are using WampServer 2.4
Microsoft Visual C++ 2012 [www.microsoft.com]
And select vcredist_x86.exe


FOR WAMP 64bit
Microsoft Visual C++ 2008 SP1 Redistributable Package (x86) [www.microsoft.com]
Yes you need the x86 Package regardless
Microsoft Visual C++ 2008 Redistributable Package (x64) [www.microsoft.com]
Microsoft Visual C++ 2010 SP1 Redistributable Package (x64) [www.microsoft.com]
If you are using WampServer 2.4
Microsoft Visual C++ 2012 [www.microsoft.com]
And select vcredist_x64.exe


If that does not solve the problem, check the Windows Event viewer for messages from Apache that may help with identifying your issue.

Thank you for your suggestion.

I installed / reinstalled all redistributables in your list.

NB: It should be noted that there were several DLLs with version numbers / release dates after those installed.

I then rebooted the system and attempted to start Apache.

The results were as above, i.e. the system generated the error message "could not initialize random number generator"

Kind regards

Can you post a section of your appache error log. Not all of it, just one attempt at startup and the resulting messages before it exits.

Also look at the Windows Event Viewer for any messages from Apache, that may also point towards a solution.

Hi -

I included the messages in the Apache error log as part of my original posting (see above).

The same six lines are duplicated each time I attempt to start Apache.

The Windows Event Viewer reports no errors.

The Service Control Manager reports that "The wampapache service terminated with service-specific error Incorrect function.."

NB: I have also tested with my anti-virus software and the Windows Firewall turned off. The problem remains.

Do you have this line uncommented in your httpd.conf?

#LoadModule ssl_module modules/mod_ssl.so

If so try commenting it out with the '#' symbol. Doe Apache load them?

Thank you for your suggestion.

I tried with the SSL line both uncommented and commented out.

The behaviour was the same in both cases: the same six error lines <sigh>

I also tried running httpd.exe from the command line. Once more the result was the same six error lines.

BTW should any environment variables (e.g. Windows Path) be set ?

Many thanks for your assistance

No changes to windows are necessary

I presumed the problem you had that lead to checking the log file has to do with starting Apache beyond the amber color of W icon .... "Could not initialize random number generator".

I had similar problem and troubleshoot for days before I stumbled unto the solution.

Check your system's environment variables...the "path" entry may have illegal symbols like "b?????Ä/????????", remove such entries. With that I was able to resolved the problem.

Even i have the same problem.can anyone give me the solution.

This may sound odd but check your Windows PATH for odd characters. This has been caused by a PATH corruption in the past.
