Hi HB, You will want NAV 2002 minimum, NAV 2003 is now out I recommend going with the latest version as it has the latest code built in. You will still need to update it. You can frequently purchase the Norton System Works for a little more money which includes NAV, Norton Utilities, Norton SpeedDisk, and the Lite version of Roxio's Go Back. Right now there is a mail in rebate coupon for $30 on the box. WMVCORE.DLL is part of Windows Media Player see; http://www.kbalertz.com/technology.aspx?tec=238&pNo=3 To get to Compatibility, go to; Start> Run> Help and Support> under Pick a Task Click on the; Find compatible hardware and software for Windows XP I hope this helps Mike ~ It is a good day if I learned something new.

Whew! However I have a few items that i need to fix, and need some help. What version of Norton Anti Virus works with XP Home? During the install, WMVCORE.DLL and WMPCORE.DLL "could not copy". What does this mean and what should I do? How do I get to the "compatibility" section? Only hardware left to configure is my webcam.
