Install Flight Sim X to second Hard Drive

I recently installed 2nd hard drive. I'd like to install Flight Simulator X on that drive.
Currently running Windows XP. Each attempt to install the game by the documented instructions reinstalls the simulator back on the C:\ drive.
Another issue I've had is with the Flight Stick Saitek X52 (never had problems before now) I've had very little luck with the tech support of the manufacturer. I've somehow placed myself in a position where I think I will have to completely uninstall the driver and start from scratch with installation so I may get the updated drivers and controllers for the flight stick. (sorry to say I CAN't afford to purchase a replacement even if I wanted to. ANY HELP WOULD BE APPRECIATED THANKS.
