Does not support Vista 64-bit. I bought this and it does not install on my Acer Vista machine. The box and details say it supports windows vista but it does not support windows vista 64 bit. I looked up the error showing when i tried to install the software, I was directed to information from the american amazon site where this problem detailed.
Very good, works perfectly and delivered quickly. One note you need a screw to fit to machine that is not provided, if you are replacing an old one fine you will have one, if fitting for the first time you will need to aquire one
