Ember windows hangs after Confirm: Do you want to proceed (Y/N): ?

I have installed ember windows and execute ember windows command on a Windows 7 system from bash executed as an admin.

It shows:

Do you want to proceed (Y/N)?
Cursor shows up in the new line after this question.

When i type Y and enter - nothing happens,
The same for y and for n.

Cursor just goes into next line and i can type and type and press enter and nothing happens. No errors are displayed

Expected result:

I type y and the process goes further.
