I would agree that forced updates are the best way to go.

Thanks so much for the info.....still reading the Brian's book.

While we use the software internally, it is an external product.
(http://www.goldmail.com) Anybody can sign up for it. There's a free
version, although I'm not certain how obvious that is from the signup -- I
think when you get to the page where you talk about $, you find the free
version there. They recently changed that, and I haven't checked it out
yet.

We haven't noticed any problems with the bandwidth. However, we are using
a Content Delivery Network to deploy the application widely. We have
thousands of users, and hope that number grows, and we need to have a
scalable solution. Internally for QA purposes, we deploy our app for about
30 people on our local server, and haven't had any problems with it.

For testing, if you are running IIS on your machine, you can deploy to
your own web server by publishing to http://localhost/appname. I do this
for testing the deployment, and then install it on the same machine, or
sometimes a different one.

Our application is only about 10MB. When the user installs it the first
time, it checks for .Net 2.0 and installs as a prerequisite if necessary
(from MSFT's website). I think we've had some issues here and there with
that, especially on older machines. (Technically, we only support XP and
Vista).

Every time the user runs the app, it checks for an update. If there is
one, it only copies over the updated files. It runs really fast. We're
considering doing forced updates, and it runs so fast it's almost
negligible. There's no additional chatter, until the user exits and runs
the app again.

ClickOnce also provides an API, so if you don't want to do automatic
updates through the deployment, you can put an option on a menu and let
the user check for updates. We weren't keen about this, because we all
know how often we voluntarily update anything. :-)

Robin,

Is your Company's ClickOnce implementation for internal software or
external users? Also, what have you noticed about the bandwidth
requirements of running a ClickOnce application? Is ClickOnce very
"chatty" or does it require careful planning to contain bandwidth costs?

Thanks!

Jim

The machine you are trying to install it on -- what OS is it running?

Thanks for the responses RobinS and Linda.
I apologize, because I neglected to tell you that I had already checked
3.5
Framework and 3.1 Windows Installer as prerequisites. Below is the text
from
the "System Update Required" dialog box thats displayed when an
installed 2.0
Clickonce application detects an update requiring the 3.5 Framework.

"Unable to install or run the application. The application requires
that
assembly WindowsBase Version 3.0.0.0 be installed in the Global
Assembly
Cache (GAC) first.

More information on this system update can be found by visiting the
site
here."

Hi,

I have a Clickonce application currently deployed with .NET 2.0 as a
prerequisite. This application has been updated to use features in
.NET 3.5,
(file association). When my current app sees the available update the
install
fails because the .NET 3.5 framework is not present. Initial
installations
are fine.

How do I enforce installing of a prerequisite upon update of a
Clickonce
application?
