Did you download the driver and put the zipped download in a folder as PP suggested? After you put the zipped download into a folder you created, did you open the zipped file into the folder you created, using 7 zip to open the zipped file PP recommended?
You can use what ever software you wish that will unzip a downloaded file, but it needs to be unzipped before you can use it. Personally I use WinRar but it does not matter if you use 7 Zip or WinRar, as long as you can unzip the downloaded file into a folder you created
