Basically, all you need to do is add support to your first version that
allows you to register files _IF_ you ever choose to include new OCX/DLL
files, re-downloading the entire setup is both unnecessary, and time
consuming for the end user (something they will most likely not thank you
for).
e.g.
'//...... download update file
If ThereAreUpdates Then
'// prompt user or whatever
If UpdateRequiresNewDLLorOCX Then
'// Call the register routine once you've extracted
'// the filenames of the ocx/dll files from your update file.
End If
Else
'// whatever
End If
Something along these lines would basically only require you provide a copy
of the filenames in your update file, along with a copy of them online
(obviously). You then extract their filenames from the update file, download
the files themselves, and register them.
