Hi Office-Guy, nice catch on this one.
I have made the engineering team aware of the issue and we'll be adding a check to verify the user has Create View privileges, and if not, a more useful error will be given.
As for restarting the Installation Wizard, you have to delete the Connections folder ( which you know ), also delete the tables in the database, and try restarting your browser or clearing its cache. That should fully reset the Installation Wizard.
Let me know if there is any more trouble.
