download the "mini disc" to your desktop...open it and run the the upgrade batch file...I had to use "find new hardware" to install with win 7 64 bit...make sure you use the right driver for 64 bit if thats what you are using...Also, follow the instructions from ther disk to hook up the tablet at the proper time. I was not able to do the upgrade by following the ematic instructions. I also had to change font/program to open the instructions as I could not read them initially.
