I installed a .Net 8.0 VB app published via ClickOnce deployment on my computer. When a new version was released for some reason the app would not update. Rather than trying to use ‘Add/Remove programs’ (and I admit this was a crucial mistake) I just started deleted the files to manually remove all traces of the program. Unfortunately when I now try to install the new version I get the error: ‘The referenced assembly is not installed on your system’.
