Adding to this:
If I try to publish to the install directories Output folder is fails.
C:\Program Files\Easypano\Tourweaver 6 Professional Edition\Output\Project1
The reality is that the output folder "chosen" it is not the final destination and the final destination is basically meant to be a hidden folder.
Browsing to this directory finds the published tour, but if you attempt to open it you get all white.
C:\Users\%username%\AppData\Local\VirtualStore\Program Files\Easypano\Tourweaver 6 Professional Edition\Output\Project1\_swf
Like I said, try publishing to another directory like your Desktop.
