Unregister distribution does not work (nor does unregistering via register_python.bat) #710
Description
While you can register the distribution just fine, both with the Control Panel and with register_python.bat, you cannot unregister.
If you try to unregister with register_python.bat by running it twice (line 23 here: https://github.com/winpython/winpython/blob/master/scripts/register_python#L23)
Traceback (most recent call last):

This is broken in both 3.6 and 3.7 and I tried an older WinPython build from roughly a year ago so this has been broken for a while...
