--- Comment #2 from Luca sciamano@iwcdesign.com 2008-06-26 07:05:27 --- The trial and the final version are exactly the same. Capture NX works like a "shareware": you install the trial and then insert a registration code if you have it, to convert to the registered version. Please tell me if you need me to try the "trial" version anyway.
Regarding winetricks dotnet20 I have no idea what you are talking about...
