Since ClickOnce installs per profile rather than per computer, is there any way to uninstall a single ClickOnce client application from multiple profiles at the same time?
We have a ClickOnce application that we would like to remove and re-install using a standard MSI, but we don't want to have to log in as each user to do the uninstall.
Assuming there isn't anything baked in, is there a custom tool?

You could manually delete the ClickOnce install for each user. I haven't tried doing this on a large scale, so use at your own risk. However, these steps should get rid of a ClickOnce app.
Delete the deployed files. On my machine, the path to my ClickOnce deployed files is, %UserProfile%\AppData\Local\Apps\2.0. If you delete everything under this folder, it will delete all ClickOnce applications. Obviously, you'd need to do this for each user profile.
Delete the start menu shortcut. Again, this needs to be done for each user profile.
Now all that's left is an entry in Add/Remove programs. I think removing this is optional since it doesn't really hurt anything, but to get rid of it you can delete registry entries. Go through the users under HKEY_USERS and delete this key, Software\Microsoft\Windows\CurrentVersion\Uninstall\[random string associated with your app].
