Problem: You get this information, when you run my installation-script again and you have added the wine-Repository:
> A repository called 'wine' already exists. Use a different alias.
Solution: I have changed my script so, that my script delete this wine-Repository and then add this one (again).
Now You can install Autodesk Fusion to a place of your choice and I have set the downloading of the files so that they are only downloaded again if there is a newer version of them!
