Thanks much...that was quick!
I already knew about that sequence. I'm trying to get the X52 PRO up and running on Vista 64-bit and I'm having a documented problem. Everything installed (according to installer) but "Profile Launcher" is non functioning and taskbar icon does not load. Furthermore, profile editor will not load or test profiles. Additionally, the Magic Bus Drivers eventually loaded but in FSX the thumb mouse on the throttle unit is nonfunctioning. Controller works but with no preloaded profile and missing some parts of control panel (dim lights for one).
I've actually considered retrofitting the whole setup on my old XP box (but that necessitates another $150 in hardware, minimum, just to see if it will run with acceptable frame rates); the controller loaded and works wonderfully on older simulators. Don't want to return the controller--mostly because I added the extended warranty cheap on an item that is guaranteed to break sooner than later (in my experience).
If I hear from Saitek Tech Support or find another solution I'll post it here for posterity.
