Problem installing Plone 5

Hello everyone, I have problem with installation of latest Plone 5 version. Installation is performed on windows 7 computer which already has Plone 4.3.1 installed (holds site which I want to upgrade to Plone 5). I follow instructions from gitHub and on command ...\buildout I got following error:

Not upgrading because not running a local buildout command.
Getting distribution for 'Record==2.13.0'.
Getting section instance.
Initializing section instance.
Installing recipe plone.recipe.zope2instance.
Getting distribution for 'Record==2.13.0'.

An internal error occurred due to a bug in either zc.buildout or in a
recipe being used:
Traceback (most recent call last):

Any help is appreciated, thank You!
