Hello,
I am trying to add a Yes/No message box to the "Next" button on the MultipleInstancesDlg. When the user opts to add a new instance and clicks "Next," I want them to be prompted by a message box. If they select "Yes," the installation of the new instance should proceed; if they choose "No," it should return to the MultipleInstancesDlg.
However, I'm having trouble getting this to work, as the output property (BTN_PRESSED) of the custom action seems to be empty, regardless of whether the user clicks Yes or No. I suspect this issue arises because the MultipleInstancesDlg is part of the EXE Bootstrapper.
How can I achieve this if I can't use custom actions?
Best regards,
Rafael Marques
