I have a Win& box running fine and installed a CODEC I need from Pegasus. This is a commercial product and needs activation. Before one went to Device Manager and to Audio devices and then (mysteriously) you could find Audio and Video codec's that are installed. Accessing their "Properties" allowed me to put in the key etc. In Windows 7 this has disappeared (or dummy me can't find it)..... I even typed in CODEC to HELP and got no answers ! Any comment ??
