I have a Professional license, and I have created an installation package that contains a custom action. The custom action is configured to "Fail installation if custom action returns an error".
When the custom action fails, a message box is displayed with the message "There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor."
This is working as expected. I was wondering if there is a way to customize the text in the message box.
