Severe problems on getting to work jedi vim (windows) - jedi-vim

Question

i have already read a lot of threads with similar topics and the tag jedi-vim here on stackoverflow and also other pages.
But this problem still keeps me from doing my actual work :-/.
Up to now I have already tried several steps back and forth, but basically I did the following:
1. Install latest Python3.4 (32bit)
2. Got this precompiled VIM: (https:// bitbucket.org/Haroogan/vim-for-windows/downloads/vim-7.4.417-python-2.7-python-3.4-ruby-2.0.0-lua-5.2-perl-5.18-windows-x86.zip) (32Bit)
3. Installed Pathogen
4. Installed Flake8 successfully
5. Installed Jedi (systemwide?) with pip
6. Got Jedi-vim from github.com/davidhalter/jedi-vim and unpacked the dir jedi-vim-master to:
6.1. $HOME/vimfiles/bundle/ only
6.2. $VIM/vimfiles/bundle/ only
6.3. BOTH
python and python3 both work (before I ONLY had python3).
So
":python3 import sys; print(sys.version)" and
":python2 import sys; print(sys.version)" give an output.
In my vimrc I force jedi-vim to use python3:
"let g:jedi#force_py_version = 3"
And now the actual error is the following:
When I type e.g. "self." in a *.py-file he searches for half a sec and says:
E117: unknown function: pythoncomplete#Complete
-- Omni completion (^O^N^P) Pattern not found
When I want to call a function and want type the parameters, something pops up / gets faded in, but it's some unclear signs and not the actual parameters.

Your problem is that the jedi-vim completion function is never called.
The error message is about pythoncomplete#Complete, which is VIM's default, but it should be set to :set omnifunc=jedi#completions.
I feel like the last line in scriptnames (D:\tools\v\indent\python.vim) overwrites omnifunc. Don't know why and how it happens, but that's my gut feeling.
