The warning isn't about an unknown publisher, it's about the file came from an untrusted source.
I'm pretty sure this behavior was new to XP SP2. Download any potentially executable file from the internet zone and it gets marked with an alternate data stream in NTFS indicating it is untrusted and requiring user approval. Right-click your file, go to properties and right on the first tab (General) click the "Unblock" button. If you sign your files, the user will be presented with your name instead of "Unknown Publisher" and they can increase their trust level of your download.

We have an application that we sign with a strong name. We are using a Setup project to build the installer. If I double click the .msi on my machine, or copy it over the network to a different computer and run it, then it works fine. No warning about Unknown Publisher appears. However if I copy the file to our ftp server and download via ftp or http then when the file is double clicked an Unknown Publisher warning is presented. If the file is compressed, copied up, downloaded, and then uncompressed the same error occurs. I can't figure out what I need to do so that this Unknown Publisher warning will not appear when customers download our app from our website. Any help is appreciated. =================================== This list is hosted by DevelopMentorĀ® http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com
