When you unzip 522, an installation path will appear. Select the path on the desktop so that it is easy to find. A folder with the same name will appear on the desktop, and then copy the two files to the desktop. In the folder, options will appear. You select all, and then there should be a file called goldwave, reg in that folder. Just double-click to install it. Is this a plug-in? Don't download the virus. I don't think the source of the file is good, so don't install it
