Wow so many replies. Thanks for all the thoughts. I'm currently 2559 now also which seemed to work great at first. Booted the computer four times and had touch and inking abilities. Just booted again and nothing =( I even formatted the hard drive and re-installed windows and still no luck. Does anyone have a screen shot of their device manager specifically the Human interface devices? BTW pmatulew link is for the 32bit driver. Thanks for all the input!
