In the world I live in, we absolutely do NOT want users making the
decision to update or not. Updates are mandatory and must install
seamlessly without user intervention. In a commercial app I wouldn't
execute the update process this way. But this is an internal corporate
application that must have everyone using the same version.
Geez! I wish we could enforce the same policy. The university world is a
little different than the corporate world. We have applications that are
considered mission critical spread across over 50 departments and schools.
Each school and, to a lesser extent, each department within those schools
and major divisions function very independently -- very much like medieval
fiefdoms. For the well-funded, larger departments with their own internal
IT staffs, update policies and where apps are installed are determined
locally. For example, the School of Arts and Sciences serves most of their
applications from a cluster of Citrix servers. They try and avoid touching
individual work stations as much as possible since they're spread all over
campus. For them, we can't allow the update process to even run since the
individual user has no authority to update the copy of the app on the Citrix
box. Some departments serve our applications from Novell file servers and
we don't really want an auto-update process running their either.
Fortunately, the bulk of our 500+ users have the applications installed on
their work stations so we only have a few exceptions we really have to deal
For us, TMS' TWebUpdate has worked out very well. We've even got it working
pretty well with Vista by including an XP Manifest in the application that
requests privilege elevation at start-up. I'm probably going to need to
look more closely at how our apps work on Vista before Vista becomes
widespread on campus.
