It will download a setup.exe file that in turn appears to pull the components from the Web for installation.
(I executed this file and went part way through the setup process, where it says that there are three components included: Platform Builder, Shared Source, and OS Support. I didn't complete the installation process because it won't install Platform Builder unless it detects Visual Studio 2005 on the PC, which I don't have yet but have already been looking into picking up if I can get it cheap on eBay or elsewhere.

How has CE 5 run thus far in BOCHS? Is it slow at all? Does the touchscreen work?
