Apache24-x86-VC9 with mod_wsgi says, "AH00419: master_main: create child process failed. Exiting." and won't start

Question

I am trying to install WSGI capability on my Windows version of Apache24. When I try to start the service I get the following in my error.log:

It is the error AH00419 that I cannot figure out after DAYS of research.

So, let’s back up. These are the steps I took previous to getting this error:

I copied the mod_wsgi.so file out of the mod_wsgi-4.4.21+ap24vc9-cp27-none-win32.whl archive using WinRAR.

I copied it into my c:\Apache24\modules directory

I added this line to my httpd.conf file: "LoadModule wsgi_module modules/mod_wsgi.so"

My Python27 is 32-bit

My Apache24 is 32-bit and is the VC9 version

I have installed Visual C++ 2008 (VC9) 32-bit

Apache24 starts up just fine if I comment out that "LoadModule... ...wsgi" line.

I can't be the only one that has run into this problem but I have been unable to find a solution online. Can anyone help?

I am not sure whether you have found the answer already since the question is more than two months old. Anyway I faced exact same issue. I used following combination of software.

Apace 2.4 VC9 32bit from https://www.apachehaus.com/cgi-bin/download.plx#APACHE24VC09 mod_wsgi for Python 2.7 32bit from http://www.apachelounge.com/viewtopic.php?t=5143

After apache installation and loading the wsgi module I got the following error.

After that I ran "netsh winsock RESET" which was stated as a solution in some other forum but didn't restart the computer though it prompted me to do so. But it didn't make any change in the situation.

Then I found following question here which gave me a clue that I might be missing some configuration.

Tool to upgrade current python installation

I added following lines to my httpd.conf

WSGIPythonPath "C:/Python33/Lib;C:/Python33/Lib/site-packages;C:/Python33/DLLs"
WSGIPythonHome "C:/Python33"

Then Apache started to work fine.
