I tried to start developing for Microsoft Surface. For that I first installed Visual Studio 2008. Then I followed this guide:

However there it says that only Windows Vista is supported. I'm still running Windows XP on my laptop and old PC and I don't want to update if not absolutely necessary. So I wonder if it is really necessary to use Windows Vista or if it is just a recommendation.
I already tried to install it on Windows XP, but every time i start the Surace SDK installer, the following error message appears:
This installation package cannot be installed by the Windows Installer service. You must install a Windows service pack that contains a newer version of the Windows Installer service.
So I was wondering if this is the problem because I don't use Windows Vista. And if not, how can I solve this problem?
Yep, probably.
You can try installing the latest version of Windows installer.
