See this manual. It may help.

The Enchanted Carousel Annex Instructions - Wrebbit.pdf - Google Drive

There is a video on their website:

The directions for installing the music box are in the Annex Instructions.

I have scanned the Instructions and the Annex instructions. You can view and download them from here:

The instructions tell you to sand the gears and apply lacquer. I used a dremel tool to sand the gears and bought spray lacquer for the gears. Perhaps that will help.

Right-click on the puzzle3d icon. From the box that pops up select properties. Under properties click on the compatibility tab. Check the box that says run as administrator, and the box that says run in compatibility mode for windows xp.
best of luck.

D8 pieces are inside the frames of the carousel supports

mayb go on ebay and ask those sellers who have a opened box to scan the instructions and you'll pay them? I heard these kind of instructions are 100+ pages though...
