'git: 'credential-Advanced' is not a git command.

[maybeec]

Based on the winstore configuration as specified here: https://stackoverflow.com/a/18286076
I get

Python\Python36\lib\site-packages\git\cmd.py", line 820, in execute
    raise GitCommandError(command, status, stderr_value, stdout_value)
git.exc.GitCommandError: Cmd('git') failed due to: exit code(1)
  cmdline: git pull
  stderr: 'git: 'credential-Advanced' is not a git command. See 'git --help'.
You are not currently on a branch.
Please specify which branch you want to merge with.
See git-pull(1) for details.

    git pull <remote> <branch>

I did not reconfigure anything manually, just installing winstore.
The global .gitconfig contains

[credential]
	helper = Advanced

I do not have any issues with git on my machine using it in my daily work.

Context: Win 7 x64, Python 3.6.2

I manually fixed it by setting the helper to manager.
