Hi,
Under the EULA, an upgrade version uses up the license of the upgraded
operating system. Once you upgrade it, that license is no longer valid for
XP as it has become part of the Vista license.
Now the simple fact is that technically what you propose should work,
however their may be a better way. If your Vista is Business, Ultimate, or
Enterprise, install Virtual PC into it, and then XP into a virtual machine.
You can then run SAS under it and other applications under Vista without
having to deal with the hassle of a dual boot.
Virtual PC:
