I wrote a custom installer class in VB.NET for Windows application and in Install method I am calling a dll which shows a dialog box with OK and Cancel buttons on it. If user clicks cancel button, setup should be rolled back. When user clicks cancel button, Setup is rolling back but a message box showing error no and description is displayed.
"The Installer has encountered an unexpected error installing this package. This may indicate problem with this package. The error code is 2869."
I don't want to display above dialog box. I don't know from where it comes. Can anybody help me?
