Vista - ClickOnce 404 problem

I have used ClickOnce to deploy my app to a file share on a server in my intranet. That folder is under a webserver root so I want my users to go to http://someserver.dom.com/App/Publish.htm and to get the app from there. This does not work. The initial MyApp.application is downloaded, but it is unable to download the rest of the files. The logs all indicate a 404 (Not Found) error.
Looking in the webserver logs, it is trying to download files that have "App/Application+Files/App_1_0_0_10/" in them. I have no idea why the plus sign is in there. It should be a space or a %20. I am unable to find how VS generates the Application Files path, so I can change it to something else, it seems to be hard-coded.

Any ideas?

Hi Lutz,

Thank you for using Microsoft Managed Newsgroup Service, my name is Zhi-Xin
Ye, I'm assigned to help you on this issue.

The "404(Not Found)" error is often caused by impoper server
configurations. If you use Internet Information Services (IIS) on Windows
Server 2003, and your deployment contains a file type that Windows does not
recognize, such as a Microsoft Word file, IIS will refuse to transmit that
file, and your deployment will not succeed.

So you can verify that the Web server is configured so that it does not
block download of this file. For more information, you can refer to these
document:

Please try my suggestion and let me know the result.

Any other ideas? Why is there a plus sign in the path instead of a %20?

Hi Lutz,

I don't think the plus sign causes the problem, I check my web logs and see
the plus sign in the path, but the application is downloaded successfully.

Would you please collect the following information at your earliest
convenience? It will help me get a more concrete idea as to what the exact
problem is and how to resolve it efficiently.

1. Which operating system is used on your server?
2. Which Web server is running on the server? Internet Information
Service(IIS) or third-party web servers?
3. Which .NET Framework version is used on the server?
4. When you deploy the application, did you set the "Publishing Folder
Location" to the file share on the server, and set the "Installation Folder
URL" to the URL that for the users to install?

Anyway, you can check on the server to make sure:

1. The following MIME types are set up correctly on the server:

.application --> application/x-ms-application
.manifest --> application/x-ms-application
.deploy --> application/octet stream

2. Regular users have read access to the root deployment folder and all the
files and folders within.

I look forward to hearing from you.
