This driver for NT 2000 and XP came from arguscamera.com. Unzip dc1102xv.zip into a folder whether it be c \coolcam or something else. Go into device manager and update the drivers for the camera and when it asks for the drivers location just point to the directory where you just unzipped the files to. In XP it will say the that 'this driver has not been tested do you still want to install' answer yes. I am using it in XP and it worked just fine when I used the Cool Camera suite software.
