@david-vasicek-pix123-fotografie Once you've finished creating the Virtual Tour, you click on Publish button, and you end on the Overlay Manager page. There you have the Download button.
Depending on the plan you have with GoThru, the download files might cost $10 or $35
Once you pay, GoThru will work on creating a zip file for you, with all the content, and send a link to that zip file to your email address. The zip file will be available to download for 20 days.
Once you've paid for a download, you can do as many updates, and downloads, at no extra cost.
