the Aston Shell is a replacement shell for Windows - uses less resources and enables you to customize the look and feel of your desktop among other things.

I'm wondering if it is possible to install this shell silently?

I used CMenu, but again it came up as an unkown installer. Anyone had any experince with this app?

I have made my own silent installer using WinINSTALL LE.
It installs fine and Aston becomes the default Shell, but my favourite theme isn't applied.

care to share?

second that

I visited the aston shell forums, and there was 2 threads there about unattended installation, neither of which solved the problem.

I have also emailed support, see if they email me back.

Look at this thread for some examples.
