I pulished a ClickOnce using VS 2005, and I can install the application at Server side (windows server 2003 and IIS 6) through webpage. However, when I tried to download the application setup from workstation (vista machine). 404 not found Error was reported.

I did some search over Google and some suggested to add MIME type for .application .manifest and .deploy to my website and I did, but still got the error, the IIS supposed to be able to handle .application request after adding these MIME types, right? Then Where could be the problem??

The error message in log file is listed below, can anyone help me??

First of all, I doubt this is a MIME type problem. Here are the MIME types, just FYI:

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

If you are deploying .Net 3.5 as a prerequisite, you need these as well:

.msp --> application/microsoftpatch
.msu --> application/microsoftupdate

If you have vsto apps, you need this one:

.vsto --> application/x-ms-vsto

The 404 error means the user can't access the files. Either he doesn't have privileges to the folder or you are using the wrong url. Are you deploying a publish file (publish.htm) with your application? If not, do so, and see if the user can even access that file.

Thx for the reply RobinDotNet.

Problem solved.

The thing is the default publishing action of VS 2005is to creat a virtual directory insidethe directoryhosting my asp.net website.

I setup a newsite only for publishing applications andI also set the publish directory propertyof the projectas well as the sharingproperty of the actualpublishing directory. No Problem with MIME types.
