#163 — Unable to install 3.0b3 using the Unified Installer under multiple versions of plone

According to my tests and the upgrade instructions here http://pypi.python.org/pypi/Products.PloneHelpCenter/4.0b3, you need to upgrade to 3.0b3 from 1.6.2. I can't get 3.0b3 to work in multiple versions of the Unified Installer 3.3.5 . I have tried 3.3.5 and 4.1.

On 3.3.5, the error is:
