Sure - best to hit 'reply all'.

I personally do not think that ZIP is very good for this, you will need
to rely on your customers unzipping, and in the correct order - and deal with the support
e-mails from customers who unzip them in the wrong order.  If you switch
to MSI and MSP files then the windows installer subsystem included by
microsoft will manage all this for you.  You can use Wix to build you
installer or one of many paid/commercial apps with nice GUI's etc.

This is a frequently asked question - please read the book you've bought
that describes how to use CVS (eg: 'All About CVS' which I had a hand in
writing, or 'Essential CVS' or one of many others) - and/or look at
previous newsgroup posts.

The idea behind open source ('free'dom) software is that you get the
source code and improve it.  This is what Todd and I were discussing.
'cvs applypatch' will be available when you or I or someone else writes
it and submits the change back to the project.
