installing pyapns on windows ..not that easy!

  File "C:\Python27\lib\distutils\msvc9compiler.py", line 383, in initialize
    vc_env = query_vcvarsall(VERSION, plat_spec)
  File "C:\Python27\lib\distutils\msvc9compiler.py", line 271, in query_vcvarsal
l
    raise DistutilsPlatformError("Unable to find vcvarsall.bat")
distutils.errors.DistutilsPlatformError: Unable to find vcvarsall.bat

when you get this problem you can to install visual studio 9 

I was able to move ahead  by:

1. Finding vcvarsx86_amd64.bat in C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\vcvarsx86_amd64.bat (depends on your setup)
2. Open a cmd prompt
3. Run SET VS90COMNTOOLS=%VS90COMNTOOLS% (depends on setup, seehttp://stackoverflow.com/a/10558328/2362877)
4. Run vcvarsx86_amd64.bat
5.  
6.  "C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\vcvarsx86_amd64.bat"

H:\office projects\event-notification>"C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\Tools\vsvars32.bat"
Setting environment for using Microsoft Visual Studio 2008 x86 tools.

but then i ran into this issue
