Ok, so I spent a good portion of the past couple of days working on an application. its basically a hub for stuff I release. Anyways when I try to run it on my computer I get no errors, but when anyone else tries to run it they get an error that I can shorten to "Unhandled Exception, Application Not Found" but from what I could tell this was happening only when they clicked on two different button's that was supposed to send them to a website. Here is the code for the button's.

I tried doing some research to no avail, any ideas?

 System.Diagnostics.Process.Start("https://examplewebsite.com");

  • Therefore it is extremely useful to add Logging to your application. – Klaus Gütter Sep 05 '20 at 05:33
  • Use `ProcesStartInfo` first instead of using only `Process.Start`, and ensure `ProcessStartInfo.UseShellExecute = true` and `ProcessStartInfo.Verb = "open"`. – Dai Sep 05 '20 at 05:33
  • I have just attempted to try that and I get the same exception on the other computer? Im just sitting here with a brain fart. any other ideas? – Inseptic Sep 05 '20 at 05:41
  • Are you using .NET Framework or .NET Core? If so, what version? And please edit your question so it contains your updated code that uses `ProcessStartInfo`, and please post the full exception details, including the full `StackTrace` and all `InnerException` entries. – Dai Sep 05 '20 at 06:29
  • Does the `Win32Exception` that's thrown have a `NativeErrorCode == 0x800401F5`? If so, then that means your other computer does not have a web-browser correctly configured. See my answer to this other question here: https://stackoverflow.com/a/63751559/159145 – Dai Sep 05 '20 at 07:46
