DPB: I'm having exactly the same problem. I've done all the steps to power the machine, but the game refuses to acknowledge that it's finished, even though I can see the belt attached to the wheel.
Hello!
I had the same problem, but it's working now! :-)
This was a problem with the unpatched game version which is delivered from GOG!
You need to start a manual upgrade from the original vendor to fix this bug:
- start your file explorer
- change into the Launcher-directory; e.g.: 'The Book of Unwritten Tales 2\launcher\1.0.0'
- start 'Launcher.exe' (don't block it with any firewall ;-)
..now it should check for updates automatically and should say that there is one to apply!
Choose install update and wait until download, patching and finally applying has been finished!
(this could take some minutes)
Now start the game and select the waterwheel and/or the power-cables (sorry, don't know the exact names in the english version of the game,. because 'I'm gaming the german one). Now Wilbur should say that the mashine is finished and he will suggest to speak to Gulliver for the good news!
I hope this solution would work for the english game version also! :-)
