The 8.5 beta isn’t available for sale yet, .. since it’s still in development.
The 8.1 is probably what you Bought , if you bought it here at Daz3D.
The Beta of 8.5 is only supplied as the base program, for testing,. so the Wizards, which are included in a separate “Carrara Native Content” installer, don’t come with the beta,. .
If you’ve just bought Carrara, then the Carrara Native Content installer, should be include in your “My Account” / “Available downloads”
You may also have several pages of downloads, since you’ll get a bunch of Bonus files, plus the current 8.5 Beta files.
The current beta is set to time out on November 1,.
so, you may want to hold off until there’s either a New beta version, or a new beta serial number to extend the life of the current beta.
hope that makes sense
