"To open this file, windows needs to know what program you want to use to open it. Windows can go online to look it up automatically, or you can manually select from a list of programs that are installed on your computer."
What do I do now?
You have to learn Windows and software who handle the file extension at this point, we can only help you if you have issue after the installation.
Purchase the CD like I said if you can't manage to get it installed.
