I downloaded dotnetfx.exe because something (i forget what now) required it, I think it was windows update.
I run it, and it starts going through the install sequence.
Then it stops here: http://www.yoimg.com/h/21280742-dotnetfx-problem.jpg.html
I have left this screen like this for 24 hours, it has not moved.
This is a fresh install of windows.
Any ideas why its doing this?
