actually you can install this without a umpc, i have it up and running now.
You need ORCA to edit the msi file and strip out the os and hardware checks.
You can get orca from
here
its originally apart of a 300mb download from MS, apart of some sdk, but the link above lets you download just the orca so you dont have to get all the other crap u dont need.
edit: once you get orca, open the msi file with it, look for LaunchCondition and it will usualy have a line somewhere with a list of OS's , just delete the whole line. Look in all the tables for anywhere it says a specific OS then delete the value for the OS. save and restart the installer.
