Getting mod_wsgi to work with Python 2.7/Apache on Windows Server 2012; cannot load module
The issue was that the Apache was built with VC14, but Python 2.7 naturally with VC9. Installing an Apache built with VC9 solved my issue.
I successfully installed mod_wsgi via pip install mod_wsgi on Windows. However, when I copy the output of mod_wsgi-express module-config into my httpd.conf and try to start the httpd, I get the following error:
httpd.exe: Syntax error on line 185 of C:/path/to/httpd.conf: Cannot load c:/path/to/venv/Lib/site-packages/mod_wsgi/server/mod_wsgi.pyd into server
This is already after correcting the pasted output of module-config, as it was .../venv/lib/site-packages/mod_wsgi/server/mod_wsgiNone (note the "None"). I changed the "None" to ".pyd" as this is the correct path.
I already tried to install it outside the virtual env (Python being at C:\Python27), but it didn't make a difference -> same error.
I also tried to uninstall/re-install mod_wsgi. I had one failed install as Microsoft Visual C++ Compiler for Python 2.7 (Version 9.0.0.30729) was not present. After that installation, the mod_wsgi always installed OK.
The apache (Apache/2.4.27 (Win32)) comes from the xampp package and starts without issues when I remove the added lines for wsgi. 
I need to use Python 2.7 because of a third-party module. So going for 3.x is unfortunately not an option at the moment.
Exact Python version is 2.7.13 (32-bit).
For completeness, the output of module-config is:
LoadModule wsgi_module "c:/www/my_project/venv/lib/site-packages/mod_wsgi/server/mod_wsgiNone"
WSGIPythonHome "c:/www/my_project/venv"
Update: tried one more thing:

Uninstalled mod_wsgi (with pip)
set "MOD_WSGI_APACHE_ROOTDIR=C:/WWW/apache"
And pip install mod_wsgi again

Still the same error...
