ClickOnce 404 - no deployment files at the Update location

Hi All,

I've been successfully deploying clickOnce successfully through the 2.0 and
3.X frameworks, but now have a problem with ClickOnce updates in 3.5 SP1.

The scenario is this: I want to deploy an *offline* application that can
only be installed from behind our organizational firewall (a Win2k3 domain),
but can be updated from anywhere (hotels, etc).

To do this, the publishing folder location is set to a UNC share path:

\\MyServer\OurD eployments\This Deployment.

And the update location is set to:

So, what we see is that the deployment files all get happily copied to the
UNC share, but nothing gets copied to the update web site. This seems
reasonable. (btw, the update web site was correctly created, using the vs

When we go to the UNC share and run setup.exe to do the first installation,
it fails: "Cannot start application".

The details accessible from the error message form indicate that the
Deployment URL is pointing to the UNC share and the deployment provider url
is pointing to the the update web.

It seems that the .application file on the UNC share is immediately trying
to get a version of itself from the update web!? Pls see below:


Below is a summary of the errors, details of these errors are listed later
in the log.
* Activation of \\MyServer\OurD eployments\This Deployment\myap p.application
resulted in exception. Following failure messages were detected:
+ Downloading
http://my.fullyqualified.srvr/Deploy...pp.application did not succeed.
+ The remote server returned an error: (404) Not Found.


Interestingly, If I publish an update, nothing is written to the update web,
it only gets written to the UNC share.

So, is this *by design*? If so, then how do I configure ClickOnce to work
correctly for my scenario. If not, any ideas?

Kind regards,

I've been playing around with ClickOnce today, and it's all good stuff. Except, that if I change my application to NOT be full trust (which seems to make very little difference to the user prompt, which scares me!) but to be installed on the start menu, it seems I don't have permission to call CheckForUpdate()! I understand that if I'm not a full trust app, I can't read the filesystem etc., but not being able to update myself seems a bit...

I have a SmartClient/ClickOnce app that needs to be deployed to a whole bunch of sites. The app.config would have to be different for each site. I am trying to do this in an automated manner (by calling MSBuild). So MSBuild builds and publishes the app - in the process it takes all the files and creates a hash. The problem is that the hash would be different for every site (since app.config is different). Is there a utility (or an...

Hello Gurus, Is it possible to schedule a task to run an application deployed using ClickOnce? The executable changes location with each update.. and if i were to run the executable directly, it's not considered as a network deployed application and it's not able to use any of the update features programatically.. any ideas? workarounds? thank you,

Hello, I would like to use ClickOne but we need to stagger our update process. Currently we are shipping cd's when it is time for an update. We stagger the release in waves of 250 each so our clients do not overwhelm our support staff with loading questions and new feature questions. ClickOnce will elininate the CD cost and the loading questions but that still does not take care of the calls for new feature questions. I would like to...
