Opening and running the downloaded files
Uncompress the zip file. After running the html file inside the folder you just downloaded, the tour will start on your browser, but not all features will be available. You will need to provide flash some permissions in order to get online access to Google maps. Once you try running the file, you will get something similar to the image below:
Scroll down to "Developer Tools" and click Trusted locations.
Click on the "+" to add a new trusted location.
Browse to the folder of the tour, and select the swf file.
This file will now be listed under the trusted locations. Restart the browser tab or window where the tour was running. You should now see the google maps tab available on your tour.
Please note that if you move the tour to a new location, this process has to be repeated.
