1. You must have a schematic part that matches your footprint. (i.e. 8051_DIP,
8051_QFP)
2. In CVpcb, did you set your Preferences/Configuration to add all of your
libraries?
I am using the same wersion and I have 16dip300. I am not sure if I used the
same zip file.
3. Most of the footprints are standard (JEDEC?) and specified in datasheets and
then you pick the same one from the list. Then, I save them in my own library
to keep with the project.
If the footprint names do not match, then I look at the drawings ('Display
footprints list documentation' icon) and compare or create my own.
