Alternatively you can run the architect as a different Windows user. The set of installed courses and libraries for each user is separate. In Windows 7 and 8 it is real easy to run the game as your normal user and the architect as an administrator. Then run the course manager as either depending on which installation you want to maintain. Not sure if you can do that easily in XP though as that was before UAC allowed you to run anything as administrator while logged in as a normal user.
By the way, after resolving the resolution issue the game runs great on my Windows 7 machine and is even working good with my modern mouse (Razer Mamba Wireless). Now that you have an XP machine setup, I wouldn't necessarily change but I don't think there's a need to go all the way back to XP unless you want to play online though Kali and I don't know if anyone even plays online anymore. After a short warmup session on the range to get the player to adapt to the mouse speed and my rhythm, I haven't had anything that felt like a missed swing due to the mouse in three rounds. This game does have tempo built in but it adapts to your own natural tempo. That is where JNPG and The Golf Club really went wrong as they try to force you into their specific required tempo which doesn't feel natural to me and in real golf there are many different tempos to swings used by successful players. My scores are not so great in those three rounds but that is to be expected.
