Hi, i am using Installscript MSI type project. What I am doing is that from a parent dialog, I need to open a child dialog on a button click. Now when I click the Ok button on child dialog., the dialog is not closing, but it hangs. I had used both EndDialog() and ReleaseDialog() funtions, but they are not working in my case. Please find the attahced demo project. I am in urjent need of the solution. Please help me....
