FTDI USB driver problems with Acer Aspire One

I recently got an Arduino Duemilanove with a ATMEGA 328 chip and wanted to set it up on my Acer Aspire One runing Windows XP home; ever thing went fine until I had to install the drivers and then I got a install error. I've tried everthing including downloading the driver from the FTDI web site. If you have any ideas please suggest them.
