I downloaded Direct X(103 MB) installer of whose custom prerequisite i wanted to create. I created it'scustom prerequisite. It got added too in my prerequisite list.
I launched my application and i ran it. It asked me that do i want to install direct x as it is a prerequisite. I said yes and it started installing.
But in mid of installation i am getting error: Cannot download the application. The application is missing the required files. Contact application vendor for assistance. I am using the exe file of complete 103 MB installer for Direct X still getting this error.
I also get this error at times that Cannot find the file DSETUP.dll but it is present in my prerequisite.

I don't think this error has anything to do with the prerequisite. It is failing on the actual ClickOnce part of it. See the 404 error? It means that there is a file in the manifest of your deployment for the ClickOnce application that is not on the server.

Try installing just the ClickOnce part by invoking the application link:

http://daisy-ef650c3c7/Test_Installer.application

Does it work? Probably not, you should get the 404 error. Also make sure you have privileges to read that folder on the web service.

One thing I will share about DirectX. You don't have to deploy the whole thing as a prerequisite and install it in the GAC. You can deploy the dll's that you actually reference locally. If you are interested, post back and I will post that information.
