How do I diagnose "Microsoft .NET ClickOnce Launch Utility has stopped working"?
- by Xaero
Hello StackOverflow!
We deploy our application using ClickOnce, installed from a file path. For 24 versions it has been working perfectly - now, on version 25 I get the following error once the application has installed and it launches:
If I test a previous deployment on the same machine, it works.
Where can I even begin to look to find the cause of this error? I already checked the windows event logs - nothing.
EDIT: I noticed that while the dialog is displayed, a temporary xml file 'WER561D.tmp.WERInternalMetadata.xml' is generated in my temp folder. Here is the contents (it might contain clues helpful to those more knowledgeable in this area than I):

Another key point is that I am publishing via Visual Studio, there is no manual manifest editing going on.
