The original problem with publishing the Explore Norway site as a install template was the size. All the pictures and the database site meant it didn't fit within the max size of Nugets.
We have added support for downloading the content files and the database from our servers as part of the install process, rather than being part of the actual Nuget. This means we can keep all demo sites within the same install template, even as we add more sites later. The additional space for the Explore Norway site was less than 5MB.
Update the https://www.nuget.org/packages/Relatude.Demos package to get the updated install template.
