I have a normal project and use ClickOnce. Today, following a new implementation, ClickOnce did not work. So I used a setup. Now that the day is over and that I have spent several hours trying to fix ClickOnce by every possible mean, it simply won’t work. It publishes fine, but when installing from there, it says that it stopped functionning with the following error:

Microsoft .NET ClickOnce Utility stopped functionning

Is there a way I could just reset all ClickOnce to default like I never used it? I can’t find any, but it has to exist.

Thank you!

    After A LOT of trial and error, I ended up fixing the issue. In the project’s properties/security menue, I unchecked the ‘Activate ClickOnce security parameters’ and published. It did recheck the box by itself, but the application published and launched successfully.
