I've installed QGIS on several dozen WinXP computers. The only case 
where I had to do something "unusual" was on WinXP pre SP2. In these 
cases I added the MS Visual C++ redistributable package from:

Have a look at this forum post:

Other than that, it most certainly works... I think cleaning out traces 
of older QT installations would probably help. (If you don't need that 
software anymore)
