Disabling Cancel button - InstallScriptMSI project

[MiltonNet]

I've been strugling with this for long. I want to disable cancel button during deferred custom action (which launch external application). I tried different ways like Disable(CANCELBUTTON), StatusDlg.EnableWindow() as well as custom action to disable the cancel butting but nothing worked.
I am using Installshield 2008.

Is there a way to do achieve this?

Thanks in advance.

You can achieve this by the following piece of code:

hCtrl = GetDlgItem(hwndDlg, BUTTON_CANCEL);
EnableWindow( hCtrl,FALSE);
