What I find when searching Silvercrest is a cassette player with MP3 connections to a computer. If you are referring to a CD that came with the player, it is probably software to manage the recording process.

You should be able to insert the CD left click on Start, click on "Run" and follow directions to locate the CD. Setup information should come up when you find the D drive.

Another option is to right click on Start, open Explore, find the D drive and take it from there. A file with the word "setup" should get you started. Some instruction should have come with CD directing you to the necessary steps.

The Silvercrest may only record to Ipod software. Which would be fine if you intend to use the recordings on Ipod. If you want recording to be burned to a CD, this may or may not work. Similar cassette players that connect to the computer via USB are available and that does seem to be one of the simplest means of converting from cassette to mp3s.
