Using ClickOnce to deploy an applicationwith a Data File for download/install from a web page. All works fine -- FTP shows that the manifest files are on the web page along with an App_Data folder that contains the data file (named like mydatafile.txt.deploy. However, when attempt to install, an error condition shows up:
"Downloading http://.../App_Data/mydatafile.txt.deploy did not succeed. The remote server returned an error: (404) Not Found"

I know the file is there since I can see it using FTP. So how could it be not found when doing download?

I've tried to install from the web page on both an XP and Vista computer. Same results.

Any advice greatly appreciated.

After lots of experimenting I found answer:

The folder App_Data which we are advised to use to hold datafiles in ASP.Net 2.0, apparantly blocks ClickOnce access during the download/install process. I moved the file to the main directory and it downloaded fine.
