Nagy -- could you post to the python-win32 list? There's nothing wrong 
with putting it out here, but I don't know if the pywin32 guys hang out 
here, and I know they definitely do there. (Which is also lower volume).

I'm not seeing any changes to the win32service code, but a "missing DLL" 
error is almost always about some combination of permissions / UAC on 
install. Adding anything to your PATH is unlikely to help (unless you 
have a truly outlandish PATH).

I'll try to reproduce later if I can but I don't have time right now.

Python 3.4 does not run any bdist_wininst postinstall scripts. Try to run `C:\Python34\python.exe C:\Python34\Scripts\pywin32_postinstall.py -install` manually from an elevated command prompt.

Much better when ran as an administrator:

I wonder why is a difference between 2.7 and 3.4 in this?
