I've got something working with the postprocessor to allow for
incremental updates. There are several things I need to clean up, and I
need to add a "backup plan" that would revert to the old version if
there is a problem copying files, but it works. My starting point was
the SelfUpdating Quickstart. The AppStart exe launches my "real"
application which is nested in a folder named after the version number.
The "real" app contains the code to launch the updater. Basically, I
added a parameter to the AppStart config file called "previousVersion."
In the postprocessor, it grabs the base directory for AppStart, and
appends the previousVersion number on the end of the path as the source
folder, and uses installedVersion for the destination path. A function
then copies files and folders from the old version folder recursively
(if they don't already exist in the new version folder). At some point
I can post some code, but there are MANY areas of the app where
customization has occurred, so eventually I'd like to zip up the whole
app as an example. FYI: I also converted all absolute links to relative
links in the config files and code, so we never have to rely on the app
being located where we "think" it will be on the user's drive. To be
continued...
