patrik. I don't think any of these errors actually matter. You normally see a lot of errors in the shell when running an application on Wine, simply because there are many functions not implemented in it yet. It is far from perfect. Your first step certainly seemed to complete, despite the errors.
Code:
wine: configuration in '/home/patrik/.adewine' has been updated
There may well not be a problem with your wine version, and you have now finished with winetricks. Try the next step of installing the dotnet framework. Don't forget to set the WINEPREFIX in your shell before you do.
Good luck.
