The disc should have an autorun file which loads the setup file when you insert the disc. It is possible you have disabled the autoplay feature. Regardless, with the disc inserted into your cd rom device navigate to My Computer. Right click and choose either Open Autoplay or Explore. If you chose Open Autoplay the setup file should be executed and the install begun. If you choose Explore a new window will open displaying the files on the disc. Simply scroll down the list of files until you locate Setup. Double click on it and choose Run. If, for some reason, you are unable to do either you can click HERE and download the driver. Save it to your desktop then double click on it. Follow the on screen prompts from there.
Also, while we welcome your questions and are happy to assist you we ask you not create multiple post dealing with the same issue. You now have four post regarding this issue. Please do not do that in the future. I can assure you it will not provide with an answer any faster than a single post.
Thank you for your cooperation.
Edit: I have had the multiple post either deleted or merged. We are good to go now. Let's proceed with the task at hand.
