Re: Protel2004 - Update PCB
The components on your board have to match exactly with the schematic components - name, pin numbers, pin names, etc. If they don't, you will get the warning list that you are talking about. It allows you to choose what action you want to take - the software will also ask you if you want to manually try to match the components, skip the update, etc. This last step is where you get to tell the software which footprints you want to match from the schematic to the PCB. There are also checkboxes that you can uncheck if you don't want the action specified on the list of warnings (ie - remove, update, add, etc).
