I just finished installing Sitefinity and everything seems to be working fine. I can edit the two sample sites with no problems. I run into an issue when I try to create a new project using the "Project Manager" tool. The error is:
The account, you have authenticated with, has no permissions to create virtual directories. Please make sure that windows authentication is enabled.
I am logged in as an admin and windows authentication does appear to be turned on.
I am on a machine running Vista with IIS7 installed.
