halo 2 editor problems

[UnevenElefant5]

k so i got the halo 2 and then got the xp patch, and the game installs fine, but i cant run halo 2 sapien :\ guerilla runs fine and i havent tried compiling anything with tool, but when i checked the debug file it said this:

============================================================================================
01.05.09 19:38:57.218 sapien debug pc 11081.07.04.30.0934.main Apr 30 2007 09:37:07
============================================================================================

01.05.09 19:38:57.218 ### ERROR this machine isn't vista!
01.05.09 19:38:57.312 ### ERROR failed to initialize rasterizer

how can i fix this? would and emulator work? and if so, where can i get one?

Are you running it on XP or Vista? "XP Patch" could mean either.

i got the vista version and patched it to run on xp
