    Everything works fine if ideally you click Next. But when the Home button is pressed in VerifyReadyDlg, the next button in CustomizeDlg is difficult. I am getting error 2856.

    Error 2856. Creating A Second Copy Of The UsageDataDialog.

    Hello,

    I created an updated dialog. I ran into this problem when clicking on the back control button.

    Bug 2856. Make a second copy of the <> discussion.

    I have already created many other dialogs, but did not face this problem.

    Small background,

    Dialogue A: A dialog has been created next to the game with two “yes” or “no” buttons. If so, discussion B is displayed. If you click No, the dialog box that opens is closed.

    When you click the Next button, the B-dialog is undoubtedly displayed

    Dialog B: The back button in Dialog B works in two ways.

    If (OLDPRODUCTS <> “”) -> be sure to open the C dialog box
    If (OLDPRODUCTS matches “”) -> go to April Dialog

    Subject: Error 2856. Create A Second Copy Of The UsageDataDialog.

    I reproduced yourproblem and I’m afraid that what you are trying may not be possible. This could be due to the

    behavior. be because ofShow Specific Child Discussion – SpawnDialog

    event. This event notifies the installer to create a subordinate dialog with a specific modal dialog while the current dialog is ongoing.

    Since you are using it to go to the next dialog, launch dialog A, you can also include it in the taskbar, 2 uninstall dialogs for the installer (A and B). The only way for the public to close Dialog A is to return directly to the child dialog. This is a Windows Installer limitation.
