We are using InstallShield 2012 Spring Professional Edition. For the last 3 years we didn't met with a requirement for a new custom dialogs in our setup.
Now our customer needs to read the details of Server IP and Port and other information related to server, so that we need to create a new custom installation dialog. For the same, when we click on the Dialogs sections in User Interface section InstallShield crashes with an error dialog.
We are getting below error message when we click on Dialogs.
