I managed to build my own pywin32 223 wheel, details here: mhammond/pywin32#1172

The problem is that there's no old version of pywin32, which supports Python 3.4. Let's see if maintainers can publish it.

I think, this might become a solution: https://github.com/cherrypy/cherrypy/compare/bugfix/limit-pypywin32-ver-for-py34
I'll wait for tests at Appveyor and then merge

Perfect, it should work and avoid the issue on further relases of pywin32. Thanks!

If someone else is a bit stuck with this dependency problem:

I'm trying with a workaround until the next Cherrypy release. Basically I'm installing the cherrypy dependencies, pywin32 221 and finally installing Cherrypy with the --no-dependencies flag of pip.

wine pip install -r requirements/cherrypy.txt
wine pip install cherrypy==14.0.0 --no-dependencies

cherrypy.txt (From the install requires of cherrypy setup.py)

six>=1.11.0
cheroot>=5.9.1
portend>=2.1.1
pywin32==221

I have a working 221 wheel that I made from a exe that I found on sourceforge) but I suppose that it works with the 219 too.

You can also have constraints.txt:

pypiwin32==219

And do:

pip install -c constraints.txt cherrypy

Perfect, everything seems to be working again :) Thanks!
