I have a ClickOnce app that has been working fine for a couple months, until a day or two back some internal politics borked the server. The result of this was that the path for ClickOnce during install changed just slightly at one intermediate level. It used to have /is/ in the path, and the is has changed to something else. I changed everything I could find, including recreating the whole target directory in IIS on the server. However, when I publish, though the link is correct, installation is failing. The log shows that, after checking and installing some prerequisites, the installation is attempting to go back to that /is/ path to find the app for installation.

Can anybody suggest where that invalid path is located? I have gone through every property I can find in Project|Properties, and they are correct. I have looked in App.config, and that is correct. Where else should I be looking?
