I am trying for a while installing Hg-Git addon to my Windows 7 Operating system
I have crossed several difficulties like installing Python and other utilities
In case it helps anyone, I have Windows 7 64bit and TortoiseHg and following their instructions was easy and worked without issue.
Installation
TortoiseHg Windows installers come with the python-git bindings (named dulwich) that hg-git requires, so one only needs to clone the hg-git repository to your local computer:
hg clone http://bitbucket.org/durin42/hg-git/ C:\hg-git
Then enable hggit and bookmarks in your Mercurial.ini file:
[extensions]
bookmarks =
hggit = C:\hg-git\hggit
You can verify that worked by typing hg help hggit
