--- Comment #13 from Sam Morris sam@robots.org.uk 2011-09-15 05:05:23 CDT --- On Windows, 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. :(
(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.)
