Error: Attempted to Perform an Unauthorized Operation
When this error occurs, it's most likely that you were attempting to install your site in a location that already has files and a database. The most common example of this is installing in a location where you've previously installed a site using MakeDNNSite. There's both web and database files in the directory, and they're currently locked and/or in use.
When you click OK, you'll also get the standard files message.
In order to fix this, you'll need to close nvQuickSite, and then manually delete/uninstall the previous website database and files. There's no need to do anything in IIS.
On rare occasions, a reboot may be necessary to remove the file/folder lock as well.
