Don't waste your time installing 2008!
You can override this in the installation file:

Extract the Windows Phone SDK 7.1 install file to a directory via unzip tool;
Edit the baseline.dat in the directory like this

[gencomp7788]
...
InstallOnWinXP=0
REM original is InstallOnWinXP=1

and save;
Run the setup.exe of the directory with paremeter via running utility or command line of start menu .
For example X:\xx\setup.exe /web
The error message, for failing to meet system requirement, won't pop up again and the installation continues.
