Missing Windows 7 WiFi?

Since replacing Windows 7 Release Candidate (build 7100) 32 bit with Windows 7 Professional 32 bit purchased from windows7.digitalriver.com I no longer have Microsoft Virtual WiFi Miniport Adapter displayed in my list of network connections. The computer I use is a HP Pavilion dv6439nr Notebook PC. I did a clean install of Windows 7 Professional.Microsoft Virtual WiFi Miniport Adapter had been displayed in my list of network connections when I had Windows 7 Release Candidate (build 7100) installed. Although it sounded interesting I was not all that concerned about vwifi because there seemed to be almost no information about actually using it. Then I found out about the app Connectify and I would really like to use it.I have used Driver Magician Lite to backup both my Windows 7 Release Candidate drivers and my Windows 7 Professional drivers. Microsoft Virtual WiFi Miniport Adapter is included in the Release Candidate drivers, but is not present in the Professional drivers. I have tried right clicking on the Microsoft Virtual WiFi Miniport Adapter setup file netvwifimp.inf and selecting Install but I get an error message that says "The INF file you selected does not support this method of installation"Windows 7 Release Candidate was supposed to be the Ultimate Edition of Windows 7, but from what I have read vwifi is supposed to be in all Windows 7 versions. Perhaps vwifi was disabled in my particular 32 bit student edition, which seems unlikely BUT not impossible considering that Windows games were disabled by default. Perhaps it's a driver problem, but why would the Release Candidate have worked but not the Professional version now.
