Installation on multiple computers: the WinTV application can be installed on as many PCs as needed as long as you use the same Hauppauge device. We link the serial number of your TV tuner (sometimes it's the MAC address) with the Activation code. So as long as you use the same Hauppauge device, you can install on more than one computer.
Prodinfo.exe is a program you can run which will extract information about the WinTV product you have installed such as model and serial number, MAC address, revision, and features which can be used to identify the exact model of your product. The driver for the device must be installed in order to run Prodinfo.exe 2b1af7f3a8
