Question

I am getting the error of System.Deployment.Application.DeploymentDownloadException when I try to run setup.exe for my ClickOnce application. If run it over the network from its original location it works fine, but if I copy setup.exe from the path on the server I get the error

Can not download application. The Application is missing required files.

I need the setup as it installs some prerequisites (.NET 4) that the end user may not have.

Clicking the details button from the error window gives the following information:

COMPONENT STORE TRANSACTION DETAILS
    No transaction information is available.

The root of the problem is it is trying to download its files from the same path as setup.exe is run from (file:///C:/Users/srchamberlain/Downloads in this case) instead of the actual deployment URL (\\fs1\contractflowtool)

I have seen a few solutions, but all of them tell me the solution is to change the MIME type on IIS. IIS is not installed on the server that is hosting the files.

What else can be done to fix this besides “change the MIME types”?

UPDATE

See the second post in this thread for some test cases I ran. The summary is: it appears that the setup.exe file uses the working directory to download its files as it works fine when I run the EXE file over the network, however it fails if I copy the EXE to my local disk.

How do I resolve this issue other than “Tell people to just run it from the network path”?

---

UPDATE2:
Looking at the setup.exe file with a hex editor, I could not find my install path anywhere in it. When I changed the install path to http://example.com/Test I was able to find it easily.

Is it a Visual Studio bug that it does not save the publishing location/install path if you are using a UNC path?

Answer 1

The way I understand it, the Setup.exe file doesn’t contain your application; it’s just how Visual Studio installs prerequisites, and then it runs your .application file to actually install your application.

I tested this out with one of my own applications. First, I copied just setup.exe over and got the same error you did:

ERROR SUMMARY
    Below is a summary of the errors, details of these errors are listed later in the log.
    * Activation of C:\Users\Andy\Desktop\Video Uploader.application resulted in exception. Following failure messages were detected:
        + Downloading file:///C:/Users/Andy/Desktop/Video Uploader.application did not succeed.
        + Could not find file 'C:\Users\Andy\Desktop\Video Uploader.application'.
        + Could not find file 'C:\Users\Andy\Desktop\Video Uploader.application'.
        + Could not find file 'C:\Users\Andy\Desktop\Video Uploader.application'.

Then I copied the Video Uploader.application over to my desktop too and it worked. So it seems like if you want to install it from somewhere other than the network share, you just need to make sure that it has both files.

Other things to check, if you don’t have it downloading the prereqs from the venders website, then make sure that it is pointing to a static place, or at least make sure that you copy those files over too.

In the Publish Wizard, on the How will users install the application? page, I selected From a CD-ROM or DVD-Rom. I don’t know if selecting either of the other two options might change how it works.

Edit:
I read through your other post. I suspect that it has to do with how the different protocols handle files. I was able to get it working from the publish.html page, but I actually published it to a webserver, so that the page address was http://www.example.com/programs/publish.html.

I tried running it from n:\webroot\programs\publish.html, and it failed.

Do you have a way to publish it to a webserver? Or at least install IIS or Apache to make it into a webserver?

Alternately, just make sure that everyone has the prerequisites, and then have them click the launch link:

Edit 2:

Here is my publishing setup. It works by clicking on the install button in Internet Explorer, Firefox, and Chrome (all I tested).

It seems like the setup file is looking at the website for the .application file, so that it doesn’t need to be on the local computer.

Edit 3:

In Windows (XP and Windows 7 verified):
* Step 1 : Start menu –> Run
* Step 2 : Type ‘iexpress’ without ‘
* Step 3 : Follow the wizzard.

Once it’s done, then you can just make your own HTML page pointing to your installer EXE file.
The only thing I ran into was that the install didn’t work the first time every time. I ran it, and it didn’t extract the files. Then I instantly ran it a second time, and it worked just fine… I don’t know why yet.
