I am in the process of upgrading an unsigned Winforms application installed on a number of sites using ClickOnce. The new application has a different name and is going to be installed to a different URL and digitally signed.

I know that I can change the installation URL path using this technique, but is it also possible to change the application name? Ideally I would like to uninstall the old application and install the completely new, renamed and signed application seamlessly to the users.

I have tried using MageUI but keep getting an error "The application manifest is not signed" when I choose OldApplication.exe.manifest so I don't know if I am on the right track here.

Yes, under your project settings just change the product name etc, clickonce will do the rest. Not much of an answer I know, but I do what your asking 2-3 times a day(long story), and it's really that simple.

To be specific, change(under Assembly Information:
Product, and Title.

We have a unsigned click once application and is installed on user machines. Now we have decided to sign this application and we are able to do it successfully, but somehow we are able to see 2 applications in control panel, say APP and APP-1. And I am not able to track the reason behind it? Or is it the default behavior?
