can you post (or send to my e-mail) the link to your manifest file. Then I can check what kind of error is reported from your server. BTW, can you download the manifest file from your browser? Just want to make sure it's not a typical MIME error. In most cases, .exe files are not a problem when running IIS. But other file types (e.g. .INI) do not work by default and you have to set up MIME types.
