--- Comment #12 from Sam Morris sam@robots.org.uk 2011-09-14 11:24:25 CDT --- On Windows the behaviour is different ;)
The installer's main screen is presented, and I'm not prompted to install .NET. I think that's because I'm running on Windows 7, which already has it installed. I don't have a machine without it on, I'm afraid. :(
(There's actually a splash screen that appears before the installer's main screen is shown. I didn't notice it before, but it's missing in Wine.)
